What Is This Thing Called Twitter?

I've had a Twitter account for seven or eight months and frankly I've hardly used it because I still don't get it. I'm told that until you've got x followers then no, you don't get it but in reality I have yet to see anything interesting on Twitter that stirs the vaguest interest in my jaded brain. Even Stephen Fry, who's blog I read avidly for its elegant use of language and ideas has failed to maintain my interest in Twitter for more than a couple of tweets and as for Jonathan Ross, well his many daily tweets are rapidly causing me to re-evaluate him. Twitter is, I believe, the digital equivalent of the Kings New Suit of Clothes and those that are twittering are desperately trying to justify the time investment by professing a relevance that just doesn't pertain. I'll persist for now but I'm waiting expectantly for some shining moment of revelation.
