Is the language filter working? I've entered a few languages and the list of projects refreshes, but I see the same repos and a few don't seem to have open issues for the language I provided. Tried first 'python' then 'ruby' and got the same projects, firefox latest. Might just be something with my many browser plugins, but figured I'd offer the feedback
