I've finally found the time to sit down and write up a Twitter provider for the Social Timeline project. I've updated the timeline so that you can view your - or anyone else's - tweets on the timeline.

I also added an additional band to provide easier navigation on a day-by-day continuum in addition to the previous (and somewhat confusing at times) hour-only snapshot. 

Despite the growing number of FriendFeed users there are a lot of people prefer to use Twitter as their only method of microblogging. I know I never update FriendFeed via its own GUI but rather just allow it to aggregate the contents of my social subscriptions. Anyway, the updated, Twitter-enabled Social Timeline is live, so check it out.
