Should there be some kind of system for defining what kind of thing a post is, and maybe also for defining what kind of links there are?

[Angular-Angel]

So you could, for example, write a post that's a question, and then people could respond with answers, and then people could respond to those with arguments, and mark the links between those arguments and the answer as being either attacking or supporting, and people could respond to those with more arguments, and questions, or with comments if they just want to make jokes or whatever...?
