Here's Raph Koster talking about his proposed wikification of MMO's, Metaplace. The more I look at this stuff, the more I fear for how much random pseudo-gaming material I'm going to have to look at in the next couple of decades. "Jim, can you give us a round up of the best twenty spaces on Metaplace?" Cut to me scrolling through 73,000 incrementally different fantasy parlours. Gah.
What I'm trying to say is: I think this will probably be very big indeed. If Koster's team can get the toolset right, or even half right, this is going to be a very important aspect of how the web will working in a couple of year's time. It might not even be Metaplace the does it successfully, after all, we had There before Second Life swamped the web, and Everquest before World Of Warcraft became the best thing since sliced undead.
Anyway, take a look. It's pretty brief, but the idea is in motion:
Via the essential Alice.
