I think an important thing to take from the original post is that if you have an issue with how other people are communicating, that's your issue and not theirs. I hope the OP was being sarcastic, but there are others who are not when they make complaints like that. If you don't like people using abbreviations, you can do one of three things about it. 1.) Not use them yourself, and hope it catches on, 2.) Ignore the posts that do use them, or 3.) Stop visiting the blog all together.
Telling others how they should behave, especially in an anonymous forum, is really not going to get you the results you are looking for.
