The wiki is now present on Facebook with our new Facebook page:

You can "Like" us on Facebook and keep up with wiki news on Facebook.

Ideally, I am trying to set it up so the wiki's twitter feed will also update that page. Facebook/Twitter seems to be bugged so that set up it taking a while (if anyone knows how to set that up properly please let me know). But I'll do my best to keep both updated.
