I think a lot of people are missing the point. It's not about everyone being grammatically perfect. In the last 50 posts or so people talked about learning disabilities and some have come out with them - and while their posts may not have been perfect it didn't matter because they were coherent and effort was clearly put into them, and the message was conveyed. The point isn't to offend these people.
But when someone posts something like:
hey guys i gunna go too lake grammer dis satuday i never bean befoare can sumone ofer tips i no tha fhish are in their also what bate do i use thanks al for advise
That just pisses me off. If you are going to ask for advice, you are asking people to put in effort that they don't have to put in to help you. So put in some effort yourself into at least some punctuation and close to proper spelling and spacing so it's not an eyesore to read.
