Twitter bottlenecks & potential

I thought this was interesting. Tweets are routed through a central server, unlike Facebook or Microsoft Outlook Exchange... that's why Twitter slows down sometimes. Users with a lot of followers, like ABC News journalist George Stephanopoulos, have so many followers (nearly 1.4 million) that the bottleneck at the server. Twitter doesn't limit the number of followers - in comparison, Facebook and other social network tools limit friends to 5,000 and require reciprocal friending.

This author also suggests that Twitter could make money along the lines of how Microsoft makes $2 billion a year, with minimal subscription and access fees.
