oooh kay. explain twitter. I once explained twitter to a friend by saying "Imagine that you are walking up to a complete stranger and telling them what is on your mind in 140 characters or less." Twitter is a lot like that. People use it in all sorts of different ways, and for lots of different reasons. I use it a lot like a chat room. And it sort of lines itself up like that. some people use it to micro-blog their day. some people use it as a way to drive people to their regular blogs. some people use it to drive people to their businesses.
Let's see, some of the people on my twitter list...
the CEO of Zappos (who sometimes gives away free shoes!
NBC Cameraman (who just came back from a trip with the president and filmed Tim Russert's funeral yesterday for the family)
Geologist who works for NASA and her boyfriend and their dog.
Miss Violet and Adminnie (not that odd really as they are local to me too but they also seem to be abandoning twitter for plurk.
an ex-pat living in Bangkok (but I shun him... heh)
A nurse with Doctors without borders (i try not to think about him too much because he goes far too many places where he has to duck when getting off the airplane to avoid flying bullets)
High School music teacher
Stay at home moms
Lots of IT -techy type people
That's just a few. I have 160-ish people on my list. Some people have over 1000. I just can't follow a long or even pretend to if I have more than 200 so I trim my list pretty regularly. I thought it was a ridiculous program when I first started using it. I now have more than 28k updates in a little over a year's time.
