We're in London. Mostly applicants are based in other countries (like the US) when we explicitly say that's not an option, so they're ruled out immediately.

Over the last couple of years we haven't had many applicants via it at all - but we did hire a really great developer through it, so it's still worth it.

The one thing I would say is that it's worth setting up a hiring page generally. Then you can have an application form on there which most the lower grade candidates just bounce on anyway.
