Something feels a little wrong about having to rely on a company that defines itself as a social media analyst to discover fully 15% of the Twitter users that follow more than 2,000 accounts on the social network identify themselves as "social media marketers." that of the people who identify themselves as marketers, 15% follow more than 2,000 people compared to 0.3% of total Twitter users following more than 2,000 people. Yet this is one in a set of ten interesting statistics to come out of a report by social media analysis company Sysomos on Twitter usage.

A summary of the 10 most interesting points from Sysomos' report was done by the Rohit Bhargava, and includes info-nuggets like the fact that over half of all Twitter accounts are inactive (have not posted an update in over a week), and that the top 5% of accounts by volume of updates are responsible for 75% of the updates published on the site. Unfortunately, some of the statistics given are tenuous at best. For example, the report contains a claim that 65% of Twitter users are under the age of 25, but as Bhargava points out, less than 1% of Twitter users actually disclose their age.

Putting together meaningful statistics on Twitter is an admirable, but near impossible task. There are simply too many variables, and not enough data to go on; Twitter's minimalist approach doesn't give analysts much to go on. Further, as David Pogue recently pointed out, users can easily change their usernames, significantly muddying the water.

So, what do you think - can we trust the numbers that are put out by social media analysis companies? Is this information useful, or is it akin to reading tea leaves?

Venerable New York Times technology columnist David Pogue recently posted a list of his productivity tips and tricks that allow him to be uber productive. The list is good in that he tries to generalize and talk about ways of doing things instead of specific software or hardware. For example, Pogue talks about using macro utilities instead of specifically naming utilities like Quicksilver for the Mac or Launchy for Windows.

While some of his tools seem somewhat outdated, it's not a surprise given the time investment he has in them. And really, although we all to a greater or lesser extent have a case of "shiny object syndrome" and need to try the latest and greatest of everything, the truth is that if a tool is working, the most productive thing to do is to just leave it alone.

Of particular note (at least for me) is Pogue's first tip that he uses text expansion software. It's not so much that he uses it, but how he uses it that intrigues me; Pogue has expansion words configured for even the smallest word. For example, to type the word "the" he needs only type the letter "t". That's some serious configuration, but I can definitely see how it could be very useful once in the mindset of always using abbreviations.

What do you think of Pogue's tips, and what is your best productivity tip?
