1. Reputation score I'm hesitant over reputation score. Reddit has enough problems with karmawhoring and spamming, and I feel it would lower the tone and empower those appealing to the lowest common denominator. While I never participated in Digg, I'm also aware of the "Power User" problem there.

2. Profile pics I'd quite like images - IF it was possible to turn them off and choose between seeing them or hovering to see them. Also if it was possible to block certain user images. I'm not prudish but I don't particularly want to see cocks and vaginas or something every other comment. Cute cats, flowers, people's real faces: fine.

3. Self-posts only No - sometimes I want a one-click link. Often in fact. This is a social news site, not a forum. If people want a more "buried" experience, they can use a forum. I actually want the front page to be a list of useful links that can "just get".

4. New users limits No opinion on this, as I have no idea what new user misbehaviour is like. What I would say thought is that currently, while operating from a fairly tight member base, the balance should be tipped towards encouraging new users rather than freezing them out.
