a little twitter in my ear

Michael Porter, aka Libraryman, sent me an invitation to join Twitter (a site where you log in and tell it what you're working on, and see what your friends are working on).  So I did.  And then I added a whole bunch of friends.  And then I played with it for a couple of days...and realized that I have no use for this whatsoever, really.  But that's ok.  As David Lee King says in his post, Twitter Explained for Librarians, or 10 ways to use Twitter:

With emerging trends, you really should play with the stuff you’re interested in, and let others mess with things that don’t interest you. But then - and this is important - SHARE.

So yes, I didn't find Twitter that useful at all.   CNN and BBC had Twitter feeds that I subscribed to, but I already get more finely-tuned news from them via RSS in my areas of interest only.  Even so, I could see its usefulness for work-groups who need to keep track of individual progress.   I think it would also be useful for keeping track of random thoughts you have that you don't want to lose (but there are other ways to do this too with other free tools). 

At any rate, try Twitter, or any other new start-up that you're willing to give a go, and share with the rest of us.  Tell us what you learned so we learn from your experiences.  A great place to keep up with new and emerging tools and web services is eHub, one of my favorite sites.
