I have made a post on another stack exchange site in the Meta section.

The issue is, what idea could be good for one of the sites, may not be good for the other and as such the question will not get exposed to the full audience if cross posting is not allowed.

So, to save me writing two questions, the post in question is http://meta.english.stackexchange.com/questions/3598/is-not-a-real-question-a-misnomer 

My questions are:

1. Is cross posting OK
2. Does anyone agree with the suggestion in the post?
3. Do I need to re-ask the question here as the title of this post has nothing to do with the post I'm citing.
