For me English is a fourth language and the way it is used in my country, as long as you understand what the speaker / poster is trying to convey, it is usually enough.
Canonrumors is a forum where the users are spread all across the world - some with good English and some with not so good English. I feel that there should be some leeway as long as one can understand what a poster is trying to convey. That said, I've seen many native English speakers who have worse English language skills than myself
I would bet that nobody is going to stop posting on the forum simply because they did not know the nuance of a language.

I come here to learn something new, not to learn how bad my gear is - I know that already ;-)!
