ah, yes. i hate that. i know that people probably look down on me because i refuse to use capital letters, but honestly, at least i'm not saying "fuk u guys i cn spel!!!!!"
Yeah, there's nothing wrong with not capitalizing. I capitalize freakin' everything because I've gotten used to it. But I have plenty of friends who just don't because they don't feel like it. But yeah, the netn00b way of speaking (ie: "omglol u r so dum!!11") drives me up the wall.
