I'm pretty sure I could get bored with SL in 90 days, and I have a pretty open mind. Most people just don't want a second life.

Plus the crashes are insane. No other MMO this old would be alive if it crashed as much as SL does. A 10 minute crash means I won't be playing for an hour or two (when I finally check back in). A 1 hour crash means I won't play for the next -day- or two. The average person can only handle so much!

So yeah, I think 10% is good for SL. Its a strange piece of entertainment that gets a lot of buzz but just isn't everyone's bag.
