My friend Chris Abraham notes: Second Life is a real community of real people who are fiercely-devoted to Second Life and fiercely loyal to each other. While they may have fallen off our collective radar in the last three years, the denizens of Second Life never received the memo that Second Life was a fad and that nobody goes any more.
Still think the 3d virtual world is a fad? The inworld economy, says Linden Lab reps, grew 94 percent year-over-year from Q2 2008 to Q2 2009. Now at nearly USD$50 million each month in user-to-user transactions, the Second Life economy is on an annual run rate of more than a half billion US dollars.
