I don't mind when people shorthand a bit to save time, but sometimes it just gets annoying. I agree everyone make errors and stuff, but it can be too much of a pain to read many times. I hate when people excessively use "U","R",or"LOL". Sure, use it every now and then, but when it's "R U CUMIN 2 TEH MALL 2NITE OR WUT??111!!1 LOLOLOL" it looks so ignorant.
