We can add this to the list of things SE needs:
1. A more discussion/forum-like interface for dealing with questions that are too subjective to fit in the "upvotes for most correct, downvotes for more incorrect" style the website uses as its primary interface. Pretty much every single meta should be replaced with whatever this is, and more POB-based sites should probably switch to something like this as well.
2. An iterative format to handle multiple versions of one person's attempt to solve a problem. I'm being a bit generic, but that's because I could see this being applied to "homebrew"…
