I signed up recently to twitter. I have not started using it to a great extent yet but some of the features look very appealing to me. Twitter seems to be a great example of Publish-Subscribe put to good use in social networking
Some points which appealed to me about Twitter:
1. As a sender you can choose the people to whom you send messages
2. As a receiver you can choose whom you follow and get updates from them
3. And you can stay connected wherever you are. Twitter supports multiple devices - SMS, IM, through the internet
I think Twitter was originally started to help people share short updates on what they were doing to people who mattered to them.
However read these 2 interesting posts from the twitter blog and they will give you an idea of the power of twitter and how people have embraced it.
Twitter helped transform Thanksgiving to Tweetsgiving and raise 10000 dollars in just 48 hours for a good cause
Twitter was used by people to provide Live updates during the Mumbai blasts
