I'm not sure if I really think that grammar and spelling mistakes in a post show a person's lack of respect. Sure, it is annoying when people speak in short-hand ways and I would prefer them not to. But would I refuse to answer a question, until that person asks me the said question in a grammatically correct way? No. Definitely not.
People here use 'IMHO' and 'CD' as shorthand phrases, yet they are normally not pointed out as being disrespectful. Personally, I think saying "You don't respect me because you don't use good grammar, and therefore I'm not responding" is more disrespectful than poor language usage. We're all on the same level here. While some are more wise than others, no one is above anyone else. While most of the people on here are helpful, there are some who take critiquing to a whole new level. Where will it end? Will people eventually not respond to me because of a misplaced comma? Some may laugh at this and I'll be the first to admit it sounds ridiculous. But where do we draw the line? I'm all for constructive criticism, but I fear some may need a refresher course on just what "constructive" means. If a person is writing so terribly that you can't understand what he/she is saying, or it takes an exceptional amount of thought to decipher what he/she is trying to say, then by all means, PM that person and let them know. If there are only a couple of mistakes, maybe give them a break. We can't all be Bill Shakespeare's.
Being a journalism major, I've had to learn the ins and outs of language usage. More often then not, the posts on CD have some sort of error in them. (And mine is no exception, I'm sure.) I think we must remember CD for what it is: a place to share thoughts and opinions about FIRST/FIRST-related things...not a place to learn grammar.
If there are any mistakes in my post, I promise it was not meant out of disrespect for anyone on CD. 4 realz.
