No, no, I get what you mean. It's actually pretty surprising how many people confuse the two.
But, seriously, take a look at the other shit that's going on: brb, gtg, afk, roflmao, lolwtfbbq, to name a few. Many people don't even bother using paragraphs or the spell check function. More than that don't even concern themselves with proper punctuation.

but i mean itz da interwebz, get used to it lolz!!1
