Well i don't know... The 'kids' i heard it around are between 16 and 21. I even know of some older russians (25 - 35) Who have admitted that they use it too.

Sure it's not grammitcally correct but people always forget that languages change all the time and maybe they should learn to accept new ways of speaking instead of calling everything 'illiterate' this and 'incorrect' that.

I mean N, katerinka, I bet you are guilty of saying 'Сколько время' which is not correct, but, does that mean you don't care about how you speak?
