Twitter could easily implement ads and let users upgrade to a premium account that would hide ads and provide additional goodies like analytics. Just like on Flickr, people love to flaunt their upgrades. Another interesting thing they could do would be to develop some killer add on like a location-based friend meet up deal or follower recommendation thing and force people to pay $6/mo to use it. I think twitter users would pay for anything that could help them accumulate followers or potentially meet someone new in person.
