If its a wiki in the traditional sense, it will fail here. Why? Because its just another freaking wiki that needs updating. If there was an HN-endorsed crawler that could aggregate posts/comments about particular subjects intelligently and allowed posts on that wiki to inject into the relevant parts of HN (say, to a comment or a post), then it could be a Wiki-style meta-filter on HN. Just an idea. Otherwise a technical wiki would have nothing in common with HN other than audience and launch base. People won't go back there and it won't beat Wikipedia at being a wiki.
