Twitter is (IMO), just a glorified way of people showing an interest in peoples lives for no reason other than having nothing better to do with yours.
Now I don't want to cause offence to people on here who use it, but this is my opinion on some people who use it for following certain people.
How sad does your life have to be, to follow celebrities and friends every movement each time they update it? I tried it once, and really, all you get 90% of the time is just your friends with crap like "Just bought an ice cream, LOL". Why would you use this over Facebook, when FB has all the same features, plus more. Like for example, chat? Photos?
The fact that it has nothing other than status updates just seems...quite pathetic imo. Unless that OcUK one offers more than just company offers, it seems like quite a tedious thing to follow. You wouldn't watch a TV channel which was just adverts 24/7, so why use the internet for the same thing?
