How long will it take before the grammar found in email, chat rooms, and forums becomes accepted in other media. Or a different angle, if we don't use proper english online why use it offline?

So what if it does? Languages evolve. Is that bad?

I mean, I don't think that newspaper columnists will ever be typing things like:

"/me agrees with the President"

or

"IWBNI Alan Greenspan reduced interest rates, cuz I'm broke, yo."

But colloquialisms creep into common use all the time. The Internet has its own jargon, and some of those things will find their way into the language over time too. What's so terrible about that?
