Week 2: Twitter or not?

Twitter has become a such popular site and most famous people are using it, to further enhance their popularity I reckon.
It's very good for a library to make bigger publicity of course. Since it's only 140 characters are allowed on one post- it's more like a computer version of instant message. It would certainly attract a quick read for coming event, for example.
Same as other web 2.0 tools, to twitter or not, mostly is determined by how we use it and why we use it. Since local councils are now more relaxed about this issue we've seen more and more contents from local government are on all sort of sites. The question now is how a library is to coordinate with media department and to do it properly.
Personally I don't think I would be a tweeter. I've made my delicious to twitter sites, that's it. But I do followed some people and want to see what useful info I can get from them.
