I set my twitter up a couple of days ago, and I am still getting use to it. I have been on Facebook for a LONG time now so its not much of a learning curve. I think for educational proposes it could be a great tool, and I know some athletic programs are using it very heavily to keep in touch with their athletes and to make sure they are updated. For these purposes I think it is an excellent idea, but when you start posting unnecessary stuff that I have to read, well then it becomes annoying and I start to drift away from it. This is one of the reasons that I am not on Facebook very much anymore. For educational purposes/coaching tool…yes, but for stupid updates on things that I don't really want to here about…no.
