Yeah, I've tried several different namespaces, and the only thing that responds in ns:0. I'm not a huge fan of topics, anyway — but the fact that they can't be set to MediaWiki, Project, Help, or any of the Talk namespaces means that the topic system is severely limited in its utility. The Topic system is a redundancy of ns:1. It's not something that can be used to actually further discussion about policies, pictures, other threads, system messages or anything else that's actually helpful to the running of the wiki.

Basically, Topics are there for you to go to w:c:icarly:Miranda Richardson and say how cute you think she is, or to go to Spock's Brain (episode) to bitch about Shatner's acting. In other words, it's more or less just social.
