Ignore that shitty post above ^^
If you want to get involved with class distinctions then go ahead, however.

Anyway, London is great. You'll never, ever get bored there - so many museums, parks, theatres, gallaries, bars, buildings... I know people who've lived there for years and not seen everything. At the end of the day it's like any other city - you'll meet great people and you'll meet complete wankers.
My advice would be to invest in some good facewash though
The smog will get to you in seconds.
If you want to move to the UK, here are general thoughts:
It's VERY expensive, living here. Everything will cost you at least a third more than you're used to...
Avoid buying any newspapers here, apart from maybe The Guardian. Seriously. They're all shit.
We have 5 terristial TV channels - ignore the third (ITV).
Don't buy a car if you're in the city. You won't need one and they're expensive to run anyway.
The atmosphere is different to America too... people keep themselves to themselves a lot more, if you know what I mean. People are friendly, but not so blatantly.
Ahhh, PM me if you want, I don't visit here much these days
