Could we improve the edited rationality materials link? Maybe it could link to the sequences, or a page with a name like "a field guide to the less wrong archives"?

I agree that this is the wrong place for this link to go; instead of the sequences, though, what about the about page? That's a much more gentle introduction than just the sequences index.

Or, alternatively, what about a new wiki page (much like the "field guide" you alluded to) with an a brief overview of LW topics and links to excellent articles by a variety of LW writers? There's so much amazing content on this site that we could be showing off to new readers, and a lot of it isn't in the sequences. Come to think of it, would anyone be interested in collaborating to make such a page? It seems like it'd be a fun community project. Leave a comment or send me a message if you're interested.
