Fair point but I don't think it is out of order. What I'm trying to say is that people should make an effort! A lot of it is sheer laziness - and it's that which I am criticising. We all make mistakes and no-one expects everyone to be at the same standard. However, there is no point in writing something where no-one actually understands what you're trying to say/ask for.
We could get into a whole debate here about lexicography and the way that language evolves (or devolves, depending on your point of view). A forum is a communication resource, for gaining knowledge and exchanging ideas so we can then go out and do something. I just want people to write clearly so that we can all gain something from it. I honestly don't think that's too much too ask.
You mention that you speak German and Japanese - how difficult would it be for you to read a badly written paragraph in those languages as a (possible) non-native speaker?
If someone can't write reasonable English, fair enough. If someone won't write reasonable English, then that is grounds for criticism.
Mind you, I think Voivode said it better! Good rant! Made me laugh too. Heh-heh - I think s/he certainly fell out of the wrong side of a hammock this morning.
