Might be useful to hae introduction points for people with a certain degree of preexisting knowledge of the subject but from other sources. E.g. If I want to introduce a philosophy postgrad to lesswrong I would want to start with a summary of lesswrong's specific definition of 'rationality' and how it compares to other versions, rather than starting from scratch.
I like the ideas of (1) providing an alternative video introduction, because some people like that stuff, and (2) having the last part of "what to do after reading LessWrong".
I think the rationality videos should be even linked from the LW starting page. Or even better, the LW starting page should start with a link saying "if you are here for the first time, click here", which would go to a wiki page, which would contain the links to videos (with small preview images) on the top.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
