I understand what you are saying. Simple mistakes don't bother me; everyone makes mistakes with things like "it's" and "its" and other words of that type. Also, I understand when people are typing fast and leave out a word or a letter. (In fact, I just did it myself - I said I understand when people are tying fast and had to go back and change it.)

The posts that bother me and bother most people, I think, are the ones like this:

my cat is calico she is very fat i love her her name is eepie

I've seen a lot of posts that don't even try to correct their spelling or grammer. On a different message board, someone brought up this same pet peeve and got a reply from someone saying, "I spend all day at school. When I'm at home on the internet, I don't want to worry about grammer and puncuation." (Only it wasn't written like that; I corrected the grammer so you all could read it! )

To me, writing correctly comes naturally but I have to admit, I spend at least four hours a day writing and writing correctly or nearly correctly the first time save me a lot of trouble. Plus, since what I write in my posts are most people's only view of me here, I want to sound as intelligent as possible, putting my best face forward, so to speak.
