I very much agree. Blog platforms are being used for things that are not blog-ish. But the problem is not overuse of blogs; the problem is a lack of appropriate, high-quality platforms for non-time-dependent info.

There are the various flavors of wiki, obviously. Using Wikipedia as an example is not the best choice, since such software is available.

I'm thinking about something like PG's essay page. With that as a starting point, what could one do? What kinds of features would be interesting to add? We want it to be usable by non-techies; what kind of interface/functionality does this suggest? Could/should it be integrated with a blog platform (or with a wiki, or with something else)? And if so, how?

There's a startup opportunity here, obviously. Probably several.
