ThinkUp is a free, open source web application that captures all your activity on social networks like Twitter, Facebook, Google+ and Foursquare. A great way to learn about ThinkUp is to see it in action.
ThinkUp captures your posts, replies, retweets, friends, followers, and links on social networks like Twitter and Facebook. We'll be adding more networks in the future. ThinkUp stores your social data in a database you control, and makes it easy to search, sort, filter, export, and visualize in useful ways.
