I'd offer a comparison to my behaviour on Yahoo! Answers, where they clearly laid out the permissions attached to the various levels (http://answers.yahoo.com/info/scoring_system http://answers.yahoo.com/info/scoring_system), and as such I only actively engaged on the site until I achieved the level I wanted. By not disclosing the values, we don't have goals to hit. And without those tangible goals, we're forced to focus on the journey rather than the destination.
