Jeffro reports there are new Twitter limitations on following and updating.
I’d echo yes, this seems like a good idea.
So far, my feeling is still that Twitter’s core user base will not abandon ship while they are fixing their architecture and in other ways resolving their issues. A bad sign for Twitter is that I’m increasingly seeing people use a different service as “their new Twitter” (see Leo Laporte’s first comment in this FriendFeed discussion). However, a stable, robust Twitter could still win these people back, I think.
