Well, how about rather than reposting, we just add a "featured sequence post of the day" section, or something. It'll look just like "recent posts", but it'll go through the sequences one by one.
Possibly we could just move the "promoted" functionality into the sidebar... I have to admit I never actually click on anything in the header... but I click a lot on Right-hand navigation.
No reposting so no double-ups and karma stays where it is, it's just a different way of featuring existing posts.
Hmm.. if this drew data from an outside source (like the link to OB does, a feed maybe?) we could avoid going too deep into the code. This could be little more than a template edit plus a feed hosted somewhere else. Interesting.
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.
