When I first came on SL in 2008 I tried looking for interesting groups, but the only ones I could find were "invite only." So I wonder, how do people go about joining groups? "Invite only" or "closed membership" is my biggest barrier. Since I came back to SL in 2011, there are a few open groups I joined recently but they're not too active. Also, as for the saying "if you can't find a group, then make one", who would join a group I created, especially if I have no land associated with the group? I would need connections or land first. So there seems to be a vicious circle here...
