I think it would interfere with the RP sections, particularly IC. For instance, it's too easy to read too far into a +1. "They +1'ed all of my IC posts until my last one. Was it shit? Did my character come on too strong?" What an intellectual burden that would be.It would only be for off-topic kind of posts, not RP. And I don't think displaying someone's aggregate rep in any way is useful.

RPers and GMs who join/start RPs only to immediately drop out has always been a major problem on RPG, some rep system to help as an early warning would be nice, even if it is abused in some cases. But a simple +1 system wouldn't help that much anyways. :P
