LOLCODE now has a Facebook profile: rather than join the ad hoc group that has existed for a while, you can become a “fan” of LOLCODE, proclaiming your affiliation a little more officially. It's also a better way for us to push out updates and to communicate within Facebook.
Another nice side effect is that the page is at least partially viewable from outside the walled garden: you do not to be logged in to Facebook to see the community page. As a result, I've featured the link on this site's sidebar.
