The more I think about this, the more I wish Facebook had many of the features Wave has. For example, easily starting a thread(aka "say something" in facebook) only for a group of friends which you can define on the spot would be very nice indeed. I would use that feature all the time. I think many people would.

This could be major competition for social networking sites. Let's hope they start competing more intensely.
