Maybe it’s just my perception of things, but it seems to me that Elgg has more working versions of its so-called mods (plugins). There are two for inviting friends, one for video management, a friend “relationship” mod and several others to make it turn into more of a MySpace/Facebook type of deal. There are a few *relatively* active mod developers. You could actually install them all and you’d be ready to go. BUT what I suspect is that the BP community will catch up faster than to Elgg in this area, because I’d assume most of the existing plugins can be ported over from WP to BP — I could be dead wrong on this. As for now, Elgg has a leg up on BP… probably not for very long though.
