Then again, I've seen just as many (or perhaps more) Brits write/type 'would of" (could of, should of, might of, and even had of) instead of WOULD HAVE, or would've.
IMO, that's worse than Mr. Bush's ^^ 'noo-cue-ler' (still can't figure out why someone hasn't taken him aside and given him a slap upside the head to straighten him out - he looks so pathetically stoopid ;) when he says it).
Cheers
