Asterisq released Mentionmap a web app for exploring your Twitter network. Discover which people interact the most and what they’re talking about. It’s also a great way to find relevant people to follow.
It loads each user’s Twitter status updates (tweets) and finds the people and hashtags they talked about the most. The data is displayed using Constellation Framework, a graph visualization library for Actionscript.
