Fresh from the clogged tubes of teh intarwubs…
"Even after you've soldiered past these problems, Second Life gives you very few clues about what kinds of content might be out there, somewhere in the Lindenverse. Therefore, the claim that one of Collins' critics made, "You get out…What you put in," overlooks the fundamental flaw of Second Life: new users have no idea what they could get out. Or even what's already there.
There's no question that Second Life has a lot of very happy users. The aficionados are right: if you put sufficient effort into Internet searches about Second Life content, or search within Second Life long enough, you'll probably find something interesting. Unfortunately, the investment in time is probably more than most people are willing to invest (if they even considered Googling for content about Second Life outside of Second Life). Second Life may work for the people who responded to Collins, but that doesn't make Second Life poised for growth."
Does what it says on the tin.
