But nobody will ever do it.
Everybody volunteers, but nobody follows through.
The solution isn't to totally scrap it and start from scratch. That's too big of a project for anybody to do. Just take one page at a time and improve it... bring the information up-to-date, simplify, elaborate, whatever.
LJ needs good volunteers for stuff like this. Don't tell me you're going to work on it, though ... that only gets my hopes up. Just do it ... then mail me. I may not take your change fully, or I may not take it at all, but I'll have comments on how to improve it, and at least stuff will be getting done.
I'd like to point out alanj, martmart, opiummmm, and halkeye for doing some excellent work on the code lately ... I get tons of mail from them with actual changes and fixes. It's wonderful. But I think more people could be doing this on non-code parts of the site.
