In my first question here, I brought up the idea of perhaps allowing users to selectively show/hide things from their profile page. I liken this to Facebook's 'Hide From Activity Feed' functionality.
The rational is pretty straightforward and subjective to each user. The bottom line is that we give the users more options for how they display what they've done on here.
It may be a bit hairy to implement but perhaps allowing a +/- (public/private) toggle next to each action would suffice.
