I've replied before, but I just wanted to say that I completely agree with Cyber-Sibes. The misspellings I can handle, well to a certain extent, but the run-on sentences are what confuse me most. I find it quite sad how some people talk online. I mean, it's one of their first impressions on their intelligence. People who don't know you and then they see you 'tipe lyk dis', well they won't think very highly of you. I'm not saying that you get negative impressions when you type without proper grammar, I'm just saying that people have more respect for you when you type properly.

Ok, the things that bug me the most (EXAMPLES):

1) "lyk OMG guys did u c dat? it wuz totlly crzy!!!!!!!!!!"
2) "hey my dog is sick what can i do to help him should i take him to the vet or what i'm soooo worried"
3) "HEY!!!! I'M NEW HERE! I HAVE A DOG NAMED FLUFFY! HE IS SOOO CUTE! OMG I'M SURE YOU WOULD TOTALLY LOVE HIM!"


Those are the things that annoy me the most. A few other things annoy me, but I can't think of how to put them into the examples.
