If we want to talk usefully about AI as a community, we should probably make a wiki page that summarizes or links to the main points. And then we should have a policy in certain threads: "don't comment here unless you've read the links off of wiki page such-and-such".

brynema's right that we want newcomers in LW, and that newcomers can't be expected to know all of what's been discussed. But it is also true that we'll never get discussions off the ground if we have to start all over again every time someone new enters.
