Just to pick a nit, I am under the impression that there are much more than 250 posts in the sequences given that Eliezer posted daily for about two years. (Of course we could stop speculating and count, but I can't be bothered) That would move the estimation much more in favour of a bot, but if its only feature is to save 40-50 hours, maybe there is something else we could do that simply isn't doable by humanpower.
So, the London community is arranging a Hackday where some of us will get together and code. In order to ensure we work on the awesomest idea(s) possible, we decided to ask LessWrong to add to our list of candidates. So here is the question:
What could a few developers do in a day or less worth of coding that will be awesome? Also, as a way of checking calibration, you can give your estimate for how long such a thing would take to build.
Note: While we will take ideas and voting here into account, there is no guarantee that we will actually end up choosing one or more of them.
