Anyway, I saw a link in a comment on another LJ discussion to the Open mind AI project. I really badly do not need another source of displacement this week, but it's kind of an interesting concept so I thought I'd pass it on.
Much as I like this kind of distributed information building (I'm a huge fan of Wikipedia and I used to do a lot of volunteering for various open directory projects in the days before there was Google), this particular effort does seem a bit implausible to me. But it's interesting, both in outline and in detail. It's surprising how hard some of the questions are, actually; I was really stumped by exercises such as 'Describe in not more than five sentences what you need to know to understand the statement: The dog was straining at its leash'.
