If you have been wondering what Twitter is all about, this article might help. I joined Twitter a couple of weeks ago (username is Justwilliams) and have been well entertained and far better informed ever since. The secret seems to be to ignore what “everyone” is tweeting, most of the time anyway. It’s impossible to keep up with it all anyway. Instead, pick the people you want to “follow” with care so that they are relevant to the things that interest you. There is a “people search” thingy at the top of the screen and a general search at the bottom. Beyond that I will say no more as it is quite easy (and completely free) to use. Comments from other users are welcome.
