The code for ThinkUp was recently declared 1.0, and is stable for multi-user setups with multiple services.
Using the official APIs of various social media services, ThinkUp lets you import all of your own posts, and drill down through the relevant information about them — which proved popular with other users, what topics are the hottest, and so on. No hacking or terms-of-service violation is required. Plus, since it's open source, you can find a number of plugins to extend the service to new platforms. ThinkUp is licensed under the GPLv3, and is written in PHP with a MySQL database back-end. All you need to get started is a standard LAMP server.
