Some people's responses or posts just bug me. I don't try and get "nasty" though. Usually just ignore them. Sometimes I just call people out on their crap post. It depends on the forum though... Obviously some forums have less rules than this one and things are more blunt and nasty.

Some people's posts just don't make any sense. It's like they didn't read the entire post and only picked out a few lines. I hate that! When you're asking for advice and type up like 3 paragraphs and someone just responds with one sentence and you're like..huh? Where did THAT come from? That's what they interpreted out of my post? Either they didn't read it, they're an idiot, or I'm the idiot for not typing clearly. It's frustrating and makes you feel more ignored than you would have been with 0 responses.

Some people type just to type and up their post count. Something like..
Anyone know what time it is?
Last I looked yesterday, it was 5:03am
