My opinion is that it belongs on Meta, as it asks a direct question about the SE engine. Though, Marc Gravell says that it belongs on SO because it can be used as an example and generic question about the used programming technique (URL rewriting), and he has a point _{(and a diamond, don't forget the diamond)}.

I'd reword the question to be more generic and leave it on SO.

About the others, those are more direct questions about SE-specific things, as far as I can see.
