My sense is that the LW wiki has the potential to be a good alternative for someone who wants to learn the ideas of rationality but does not have the time / patience to read through the Sequences. However, the Sequences have the major advantage that they have an order to them (actually several alternative orders - my favorite being Benito's) where someone can start at the beginning and work their way through in an organized way. To my knowledge there is nothing comparable for the wiki.

Anyone out there willing to put together an organized guide to the wiki aimed at a newcomer who wants to quickly learn through the material?
