This article in particular crystallized a thought I've had about this site, and sites like this in general. I would love to see a wiki-editable block attached to each submission that tries to describe, in as few words as possible, what information the article contributes. Think of it as compression, where a basic knowledge of computing is assumed. More interesting articles would have a lower compression ratio, which might be a fun thing to filter on. This article might go down to, "C is generally unsafe, and you probably aren't skilled enough to make it safe, so don't use it". Or maybe, "I needed to write something for my company blog, so I found a recent security hole and added some vaguely related platitudes".
