My biggest pet peeves are run-on sentences and writing an entire post in capital letters. I don't mind capital letters used for emphasis, but when someone puts their whole post in capitals, it is so hard for me to read. Run-on sentences are very difficult for me to understand -- my brain just can't wrap itself around a run-on sentence; Takes me forever to decipher it. Spelling mistakes aren't a huge thing. I'm a bit of a spelling and grammar freak, myself, but I CAN spell and use proper grammar -- some people just can't, so I try not to judge spelling mistakes. Just like I'm not good at math, not everyone will be good at spelling. I know people with dyslexia that have a very difficult time spelling, and people who have or had hearing problems that spell the word like they used to hear it.

Did anyone else notice that they made twice as many spelling mistakes in this thread as they usually would?
