ThinkUp: Social Media Insights Platform. I definitely want to check this out - a tool that collects your own social activities (well, they're not always that social) via various APIs and combines them. And in a self-hosted database. Supports Twitter, Facebook, and Google+ and evaluates the data collection according to various criteria. And with Social Timeline there is then a tool for displaying as a timeline, which could be integrated into your own blog. This could even be a much more pleasant variant than importing all posts from social networks into your own blog.
