How do I attract people to my months-old wiki? I'm the only person who ever contributes.
It really depends on the focus of the wiki. Sometimes you can make a blog post about it on wikis with similar topics (if they allow that).
Though I recommend that try to get your wiki spotlighted if you want to try to get a lot of new editors.
