More Social Media Integration/News Sources

Most of my contacts are not high profile, news-making individuals! So, I get more valuable news about my contacts through 'social' services rather than traditional news sources. So, a live stream of activity from services many of my contacts use would be more useful for me than the current 'news' I see.

This would be services like photosharing (flickr, picasa), geolocation (google location, brightkite, etc), social (facebook/linkedin status messages and whatever else the APIs allow you to pull), etc.

I find products like Xobni useful because they do this in a way where I actually discover an online connection where none existed before (via their LinkedIn, Facebook, and Hoovers integration). Gist needs to add something similar and differentiate by taking it further than just these services.
