ThinkUp is a free, open source web application that captures your posts, tweets, replies, retweets, friends, followers and links on social networks like Twitter and Facebook.
ThinkUp is a web application you install on your web server (PHP), designed to capture, organize and archive the content you create on different social networks, and to give you insights into the conversations that happen when others reply to or forward your ideas. With ThinkUp, you can ask your friends anything and easily synthesize the responses you get from a variety of channels. You can also get statistics and reports about key metrics of social network activity from you and your friends.
By archiving your content, ThinkUp gives you a copy of your social networking presence that you own and control. This preserves a rich history of the conversations you’ve had, and of the people who have responded to you. All of the information and insights that ThinkUp collects can be easily exported into simple formats that you can open in a spreadsheet program.
