I also think that SecondLife stands on its own as far as scale and ambition. And although I can imagine it being engineered better, I can't point to any other project that is similar enough to use as a legitimate example of better quality. In a way it almost seems like the inverse of Craigslist. SecondLife feels so over-the-top and sloppy that I think someone will come along with some new technologies and replace it with a leaner more performant product. But they haven't.
