Truly excellent post on "Why I use Twitter" by Dan York

This is a really great summary of how people are using Twitter and why from Dan York over at Disruptive Conversations, in summary he uses Twitter:

1.   as a News Source
2.   as a Knowledge Network
3.   as a Virtual Water Cooler
4.   as a way to stay up-to-date with friends
5.   as a Travelogue
6.   to Track Conferences
7.   as a PR/marketing Tool
8.   as a Learning Tool
9.   as Fun
10. as a Daily Lesson in Humility (and Brevity)

But it  is worth reading the entire post.
