As you may be aware, part of the reason Google's Blogger service is so popular is that it's incredibly easy to use. All files are hosted on Google's server, and all you have to do is pick a template and start writing. You can also add widgets to your site by choosing from a list of options in the layout tab of Blogger. If you really know what you're doing you can customize the HTML for your page layout or add custom widgets to your sidebar.
But even if you don't know a lick about HTML, Blogger has a few hidden tricks up its sleeve. If you go to draft.blogger.com instead of www.blogger.com, you can access a bunch of experimental widgets that Google has decided aren't ready for mainstream consumption just yet.
