> perhaps someone could enlighten me as to what I'm looking for?
You're looking for information. If you tried out Twitter and you didn't get it, you probably weren't receiving the information you were looking for. Its really amazing how people hype up Twitter and then when someone tries it out "they don't get it". There isn't anything to get but updates about things you're interested in. What you get out of Twitter is directly correlated to how well you tune your twitterstream. Twitter is valuable to me because it provides me with real time news and updates about the things I'm interested in. It really is that simple.
That is true. On the other hand, saying that someone "just doesn't get it" until they've used it implies that anyone will 'get it' once they've used it for a while.
There is a difference between not getting it and not having a use for it though, I've seen too many people complain about not getting twitter - suggesting they don't understand the simple concept. Perhaps this is a fault of the Twitter UX? I "got it" straight away.
