@SuperTim
You've made it abundantly clear that you "don't get it". No need to repeat yourself. That kind of behaviour would get you rapidly unfollowed on Twitter.
It's not all "benal(sic) d-list celebs". There are a lot of a-list celebs too if that's your bag. Plus lots of journalists, writers, experts in numerous fields, magazines and newspapers tweeting updated content a la RSS. In fact, I'm glad you're missing out. It's really great.
I don't use any of the other social networking websites although, inevitably, I've had to open an account on each of them for one reason or another. I reckon that's the case for at least 75% of Facebook's alleged users though I could be wrong. Twitter just isn't like the rest. You can refer to Twitter users as saddos if you like but it seems to me to be demonstrably much sadder to waste time slagging off what you claim to be a pointless website that you don't understand on yet another website which is normally only frequented by borderline austistic IT types with bad body odour, a full gamut of vocal and physical tics not dissimilar to Tourette's and precisely zero friends including family. 353 friends!? Dream on! I also suspect that everyone hated you at school right the way down to the janitor's dog.
P.S. If I google SuperTim will I find out exactly who you are? The super part is clearly a misnomer and doesn't look much like a forename to me.
