Indeed, and SL is a lot of fun.
Here's me, with no RL money ever invested, having fun and being picky about where i have my fun.
The game is 'corporate' and 'capitalistic' in it's nature, but those features are easy to ignore.
Oh, and that doesn't mean it won't be cool if you put any of us as the one that reffered you in SL. A little extra virtual money never hurts:)
