This was very cool to read. Yesterday was challenging -- I think I underestimated how hard it would be to produce a mixed reality event and also speak at it! I'm glad someone was taking notes.

As for the 3.7 million, I think you're right. The intent is to explain to people how many people are in Second Life and "3.7 million accounts" sounds weird -- "30k concurrent users" doesn't mean much to non-experts and the size of the true user base. . . .well, that's anyone's guess. I wish we had a better way to convey this -- what do you suggest?
