Want to know who is talking about you or your brand out there on Twitter? Want to get beyond Tweet Deck? Like pretty visualizations?

My favorite? Twitterthoughts, as it enables a little more complex trend charting and reporting on what is being said around your brand and related topics…check it out.

My favorite feature is the ability to watch a trend over time. Cool stuff, indeed.
