Sometimes you're just better off not knowing. Maybe one of those times is when someone unfollows you on the microblogging service Twitter, but now there's a service for the morbidly curious. It's called Qwitter, and it'll send you an email notification whenever your account loses a follower.

Qwitter doesn't need a password or a confirmation. Just put in your twitter name and your email address, and you're all set. You'll start getting messages when people unfollow you, including the latest tweet you'd posted before they pulled the plug. It doesn't work retroactively, so if you were hoping to figure out who's already unfollowed you, you'll still have to do that by hand. In case you have second thoughts about signing up for bad news, there's an unsubscribe link in each Qwitter email.

Google has quietly announced some new features for Analytics, its web tracking tool. They seem small, but these additional tracking features will provide much greater insight into what is going on your website since you can't always peer over visitors' shoulders to watch.

The updates include:

• Site Search Tracking - Users will now be able to tell exactly what keywords visitors searched for on your site, and where these searches end up.
• Event Tracking - Currently in a limited beta test, these website reports will show how users interact with various multimedia aspects on your site, including flash and Ajax without messing with pageview metrics.
• Outbound link Tracking - Also in a limited beta test rolling out in the next few weeks, reports will show what links website visitors click on that direct them to an outside site.

If you have a website, and don't already have the free Google Analytics code installed, you are missing out on understanding how your visitors move around, how they interact with your content and how they got there in the first place. Google Analytics not only provides insight on how people navigate, but it also aids in targeting site content towards what people enjoy. It's easy to set up, free and Analytics reports are super simple to understand.

The key to saving money is knowing what you're spending it on. If you can keep track of every cent, you can discover exactly where your money is going and act accordingly.

Spendview is an online application that enables users to track and visualize balances and expense data in one place. This is done through an engine that tags and categorizes spending in order to make your finances somewhat exciting. Spendview also uses tag clouds and a dynamic chart instead of old fashioned pie charts and bar graphs. This way you can see all of your data at a quick glance instead of mulling over numerous columns and categories.

Users start out by registering for a free account and adding bank, credit card information and tagging transactions with keywords. How secure is the data you enter? Spendview says that its 'secure', and they do use 128 bit SSL Security. However, you should always be cautious when entering private financial data online.

Other comparable online financial tracking software options include Mint, Quicken, Freshbooks and Gastus.

Have your ever been randomly searching for something online, only to realize you closed a window and cannot for the life of you remember what website you were on? You might be able to check your browser history or use a bookmarking tool. But what if you want to share your browsing records and let other users see where you've been?

Hooeey lets you record eveyr site you visit. You need a hooey account and a browser toolbar in order for hooey to do its thing. The toolbar then tracks the sites you have visited in online folders allowing you to check out analytical reports and share links.

So if you are up for letting friends know where you have been, hooeey will gladly share your browsing patterns with them.

Spend, spend, spend.... track, spend. Spending is easy, but tracking expenses and spends is not only time consuming, but tends to slip the mind every once and a while. Once you have a proper tool to aid in daily expenses you are on your way to some healthy financial data.

Gastus is a free online tool that helps people track daily expenses. Expenses can be categorized each month by type and concept, and display charts and graphs for a quick analyzation.

Will Gastus help generate more money or help you to spend less? No. But it will give you a breakdown of where all of your expenses are.

Do we care why Google bought DoubleClick? Well, it could be nice to know a little background history on the deal in progress.

Alex Kinnier, Google's Group Product Manager made a blog post yesterday as to why they decided to buy Doubleclick. Basically, DoubleClick has been a leader in the online advertising game from the beginning, helping advertisers get onto large sites such as AOL, Yahoo, MSN, CNET and ESPN.com.

Google's display advertising was seen as a little speck compared to the giants of online display advertising, AOL, Yahoo and MSN, and they wanted to change that. Google feels that DoubleClicks products and technology complement their own quite nicely, that paired with DoubleClicks delivery mechanisms can help current AdWords customers obtain more precise metrics enabling them to get a better idea how their advertising campaigns are fairing out. DoubleClicks superior knowledge in the industry will also be able to help Google's initiatives out by communicating with agencies and publishers to create more innovative ad serving technologies. Through the DoubleClick deal Google will also be able to help out with unsold media using DART, a hosted enterprise-class advertising management and serving solution for publishers.

So there you have it. It's all about helping the advertisers out. And maybe a little about lining Google's pockets with some extra R&D and Engineering dollars, judging from all of the new releases lately.

If you're a small business looking for an easy way to store and manage invoices online, Invotrak could be the solution you are after. This simple online solution lets users input, track and issue invoices to clients. Its simple and straightforward navigational structures and tracking features make this an effective way to track past due invoices, and incoming revenue without using complicated software.

There aren't many steps involved in setting up a profile and getting up and running:

• Create a login
• Add client information - client name, contact name, address, email, and notes.
• Record invoice - select client from dropdown, set date, amount, term, and upload an invoice from your standard application like word or excel.
• Enter any invoice comments
• Email to client

Through the user interface, companies can then track what invoices are out and waiting to receive payment on. When payment comes in, a simple click drops the payments to the received category, and adjusts balances in the right column.

The service was created by Draconis Software using Ruby on Rails to manage and keep track of their own invoices. Draconis says that they make every precaution to ensure information that is stored under your profile is secure. That's always great to know, but what happens if something goes wrong? Or, knock on wood worse case scenario, Draconis goes out of business? What happens to our information then? That's the main concern I always have when storing my data online. You can't get much simpler than Invotrak though, however, we would like to see a way to export information to a spreadsheet application for desktop storage purposes.

Mac users, check out the Dashboard widget so you can easily catch a glimpse of your invoices.

For another simple invoice option look at Freshbooks.

The Invotrak service is free, and super easy to use. Check out some screenshots of the interface.

Understanding where your traffic is coming from is one of the major components to being able to optimize content for a better experience for users. Having a good analytics package is key, whether its Google's free Analytics or a visually stimulating package like CrazyEgg. Throw some confetti on it, and what do you get?

CrazyEgg is well known for their visual approach to analytics. Their free offering makes its easy for website owners to get a quick look at where visitors are clicking and how they are navigating through a website with the use of heatmaps, overlays, and now with some confetti. With the analytical Confetti view, users get a better understanding how visitors interact with their website. Visitor interaction can be sorted based on referrers, search terms, operating systems, browser, time before clicks and window size in a colorful easy to understand view.

Crazy Egg is a free analytics service, with an upgrade package available. Installation is through a simple javascript line added to webpages that you want to track.

Okay, confession time. Despite being an early adopter for most things, I hadn't caught the basecamp train and got on board. Why you ask? I had no good use for it, though it is an excellently crafted application. I love software, and thus I checked it out, but for some reason I didn't see how its use would fit into my busy life, until now.

Becoming a self-employed web developer threw my daily routine out the window in a big way, and my preciously corporate sanctioned work-flow as well, giving me a new set of problems. One new problem I've had is process tracking, central information storage and updating, and project management. If this sounds like three problems, you're right, but they are tightly connected.

Having many projects and lots of information to track, share, and modify, basecamp handles with ease and makes me work less and takes care of these problems without taking too much of my time. I am finally "with it" when it comes to project management.

Developing software is no picnic (as you know), but now at least I know where the utensils are. Try eating potato salad without a fork, and you'll get the idea. If you haven't checked out basecamp (by 37 signals) it is worth it, there is a free account, awesome simple tutorial videos, and a great application to help you track life and work.

If you are with it, and use basecamp religiously (or casually), do you have tips for a basecamp beginner like me, or ideas to get more out of basecamp? We're all ears.

REKO is a Firefox extension that tracks the most popular sites that you visit and uses the information to find similar users who will have relevant links for you. How does it work? REKO gets sent the domains of the websites you visit, then adds them to your profile and compares them with similar browsers that match your profile. This can also include OPML feeds for RSS subscriptions. From there you can view the sites of closely related individuals, checking out their profiles and seeing what they are visiting.

Sounds like a great option if you are on the lookout for more sites to add on to your daily list. However, there is the privacy issue. Now, if there was a way to turn it on and off, or erase certain sites from your online profile, we could be talking about a great way to check out some additional sites we might like.

The site is still relatively small, with 25 registered users who've decided to trade privacy for shiny magic beans, tracking 4,382 domains.

UPDATE - weirdguy in the comments has let us know that you can indeed exclude certain URLS from being tracked. Thanks for the tip!

Even though the Google flight info service is currently only available for departing or arriving flights in the US, flightstats.com the supplier does offer international stats, so Google could be releasing this service worldwide.

The Google Flight Status gadget can also be added to your personalized homepage.

Google has just added an update to its popular small business Mini search tool that lets users plug into Google Analytics for tracking. With this new integration, Google Mini owners can now add Google Analytics tracking codes into data, enabling better tracking and analyzing of search results. This new understanding of what visitors are searching for will allow for the discovery of how little tweaks and changes can be made to satisfy visitors, helping them find the information they have requested faster. I have not had a chance to play with the administrator account on the Mini, but Google does say that it is a simple procedure for administrators to configure the Mini to use Google Analytics. Simply set the Analytics account number inside of the admin interface. The output formats for the search results will supposedly automatically include the JavaScript that Analytics uses.
