The social networking sites are super over saturated now. Something like that totally seems like it's late to the party. While I doubt any of us would be into it, I wonder if the younger generation would latch onto that stuff still. I have a friend with a teenage son and him and his friends are total slaves to that facebook stuff. I think I might have had a taste of it but I really don't use it very often anymore, or just in a more private way. But these kids sit around the computer on facebook! So weird. So yeah, maybe weird travel-book site will work for some people, but it really feels like that stuff is probably on it's way out.
