Gina Trapani: " When you run ThinkTank, you capture your updates on popular social networks (right now just Twitter, but Facebook is to come) and also the responses they elicit. Then, ThinkTank sorts, organizes, and filters those responses to make the most interesting ones bubble up to the top.
ThinkTank is an open source software project that's still in its infancy and growing fast, thanks to dedicated volunteer contributors who want to improve the platform for both themselves and the community."
