I know that PL got... mixed opinions about everything being tradable. Although, the affect on the activity of the game has been tremendous. I feel like making everything tradable in SL will be a good start to bring some people back. I really hate to see how dead SL is. Also from my personal experience, there is way more acc trading in SL than PL. I get asked all the time because of my rare vanities and it's really quite annoying.
