Maybe let existing users continue like today and charge only for new users?
Personally I think twitters problem is much simpler: it is just a media/subset of biz/subset of tech thing.
The only thing twitter has over other services is brand recognition and a certain community.
On all other areas they are owned by both Facebook and even Google+
I remember being exited about twitter years ago: I saw lots of possibilities like "event streams" for automated processing, I thought they'd come up with a way to mark certain messages as mostly relevant for certain groups of followers etc.
What they did instead was focusing on painting themselves into the 140 revolutionary characters corner and keeping the paint wet from time to time by messing with the API etc.
