After noting Ted's post on The Alpahville Herald, I had a look at their mission statement. Very interesting, especially (at least for me) inasmuch as they're doing something very different from us here: they're documenting the social history of one world and indeed one shard of that world. In years to come social historians, theorists, statisticians, economists, etc etc etc will all give thanks for resources such as these: deeply embedded accounts of what actually happens in-world. As Ted has noted elsewhere, it's really really hard to do research in these worlds, because they're so opaque to non-participant inveestigation.
Which leads me to ask whether there are other local histories or social accounts of various worlds. Where does one go to find out, for example, about the economic system of AC2, the social stratification of AO, the politics of There? My off-the-top-of-the-head list would include accounts of lambdamoo (and not forgetting Julian), EQ (though there are a number in this category), UO, Second Life, and now TSO. And there are the various gameboards like IGN or Stratics that are helpful but involve a lot of wading (not to mention pushing up the gain on the l33t-filters)
So where else is the social history of these worlds being written?
