Okay, so I see two solutions here:
1) put a link to "Rationality" e-book on the LW title page, and maybe also in the sidebar -- for the new users;
2) for the old users -- someone should study something rationality-related, and then post it in a form similar to Sequences (for me that means: motivating and easy to read), adding their own insights. Easier said than done, but this approximately what Sequences were about.
None of this seems related to the typical solutions on "improving Less Wrong", but maybe other people are trying to solve a different problem.
[I apologize if this is considered lower-quality content, but I felt this was too big for an open thread post, and Discussion is currently the next-lowest option.]
Inspired by the recent discussion surrounding Lesswrong, Effective Altruism Forum and Slate Star Codex: Harm Reduction, this thread is intended for brainstorming ideas to improve Less Wrong, and also for including polls with your ideas as an easy way to get an estimate of what people in the community think of them.
Information on putting polls in comments can be found here. Please be thoughtful about how you word your poll options, and (in the case of multiple-choice polls) include a "no vote" or equivalent option so that people who just want to see the poll results won't be forced into picking an option they don't really support.
Thanks to everyone who shares ideas and everyone who takes the time to think about them and vote!
