I’d read a little about Explode! last week, but hadn’t really had the chance to investigate until now, and it seems to be growing rapidly. Rather than trying to explain it myself, just search for “Explode, weekend, elgg” on Google. I’ve started adding a few friends.
It uses OpenID – which seems like a good idea. The trouble with OpenID and me, is that I have several. There are a number of sites that I’ve signed up with that say that use OpenID – and then I forget what they are … so I end up with another. Hopefully I’ll manage to remember to this one!
