You people need to read articles on why twitter is amazing, and its nothing to do with Lily Allen.
Can you not just tell me? I still don't understand the fuss.
Do you use RSS feeds at all?
Basically that, but with social networking aspects of sharing articles/tid-bits.
So, who do you follow? I mean, honestly, I couldn't give a f*** about what Stephen Fry's last s*** was like.
Mainly technology and web development things. People/Websites who post up links to various articles
Breaking news (how I got there first on the Michael Jackson heart attack thread!)
BBC & Telegraph Football (results / articles / rumours)
NUFC
I CAN HAZ CHEESEBURGER
Friends
Digg top 20
Ben Folds
iPhone dev team
FIFA losers
Johnny Cupcakes
oh, and Stephen Fry

If anything interested me, I would retweet it to my followers (friends) or if I thought anything was of interest to a specific person I'd inform them.
