Based on my observations, people can upvote or downvote individual posts, which retain their own reputations. Then the total reputation score for a person is the sum of all of the post's scores and is shown on their profile page. I'm pretty sure that's how it works.
Edit: Sorry, where will it say on on the profile page? Does anyone know? Also - are hyperlinks and stuff like that the same? Is it still the same, as for marking a riddle as Solved? Does all of that work the same?
