I suppose it means edits to pages? In other words comments on threads, blogs and such don't count since they don't really contribute much to the wiki.

If you go to your own user profile there should be something that says "More badges you can earn" at the side. The badge that says the requirements are to make a certain number of edits to articles should show you how many "namespace edits" you made.
