I finally signed up on Twitter, just to see what the buzz is all about. Not sure about it yet, I'll have to wait till I've connected with a few more people and the tweets start flowing.
Thing is, I'm already fairly active on Facebook, and there's considerable overlap in the concepts. Of course Twitter is a more public medium, and I have no reason not to keep my tweets public. But, frankly, I think pretty much all who could be interested in reading them are already friends on Facebook.
Don't know if I picked a bad time to visit, but for a supposedly simple site Twitter seems surprisingly slow and cumbersome. Even the mighty bloated Facebook seems to work smoother...
You can find me here if you want.
