As promised, here is the "Q" part of the Less Wrong Video Q&A with Eliezer Yudkowsky.
The Rules
1) One question per comment (to allow voting to carry more information about people's preferences).
2) Try to be as clear and concise as possible. If your question can't be condensed to a few paragraphs, you should probably ask in a separate post. Make sure you have an actual question somewhere in there (you can bold it to make it easier to scan).
3) Eliezer hasn't been subpoenaed. He will simply ignore the questions he doesn't want to answer, even if they somehow received 3^^^3 votes.
4) If you reference certain things that are online in your question, provide a link.
5) This thread will be open to questions and votes for at least 7 days. After that, it is up to Eliezer to decide when the best time to film his answers will be. [Update: Today, November 18, marks the 7th day since this thread was posted. If you haven't already done so, now would be a good time to review the questions and vote for your favorites.]
Suggestions
Don't limit yourself to things that have been mentioned on OB/LW. I expect that this will be the majority of questions, but you shouldn't feel limited to these topics. I've always found that a wide variety of topics makes a Q&A more interesting. If you're uncertain, ask anyway and let the voting sort out the wheat from the chaff.
It's okay to attempt humor (but good luck, it's a tough crowd).
If a discussion breaks out about a question (f.ex. to ask for clarifications) and the original poster decides to modify the question, the top level comment should be updated with the modified question (make it easy to find your question, don't have the latest version buried in a long thread).
Update: Eliezer's video answers to 30 questions from this thread can be found here.
This disadvantages questions which are posted late (to a greater extent than would give people an optimal incentive to post questions early). (It also disadvantages questions which start with a low number of upvotes by historical accident and then are displayed low on the page, and are not viewed as much by users who might upvote them.)
It's not your fault; I just wish the LW software had a statistical model which explained observed votes and replies in terms of a latent "comment quality level", because of situations like this, where it could matter if a worse comment got a high rating while a better comment got a low one. (I also wish forums with comment ratings used ideas related to value of information, optimal sequential preference elicitation, and/or n-armed bandit problems to decide when to show users comments whose subjective latent quality has a low marginal mean but a high marginal variance, in case the (")true(") quality of a comment is high, because of the possibility that a user will rate the comment highly and let the forum software know that it should show the comment to other users.)
Reddit has implemented a 'best' view which tries to compensate for this kind of thing: http://blog.reddit.com/2009/10/reddits-new-comment-sorting-system.html
LW is based on reddit's source code, so it should be relatively easy to integrate.
