If you're looking for a novel way to represent and visualise your online persona, Geek Chart takes your activity on popular sites and turns it into an interactive pie chart.
Geek Chart surveys your activity on the services and social networks—specifically, that's Twitter, YouTube, Flickr, any blog with an RSS feed, Digg, StumbleUpon, Delicious, and Last.fm. Creating the chart is as easy as plugging in your user name for each of the above services that you use. Geek Chart gets to work, generating a pie chart based on your activity over the last 30 days. Each section of the chart displays the name of the service when the mouse cursor is placed over it, and if you click the section it redirects you to your publicly available presence on that service.
Making a chart is free; embedding the chart in your website requires a sign-up for an account. If you're proud of your geek chart, link it in the comments below.
