User:orthonormal suggested (and many seconded) a better Welcome section and improvements to the About page.
User:bentarm suggested doing something with the comment help link, User:jimrandomh suggested making it a wiki page, and User:Alicorn requested that it be more extensive.
Responding to the above suggestions, we propose adding functionality to Less Wrong. We'll add a special page type that collects its content from the wiki. We propose that /about, the home page, the comment help text, and each user's user page be of this type (I imagine that this change to the homepage may be controversial).
We propose that those pages link to:
- and each user's wiki userpage if an exact name match exists.
These pages would cache wiki content for at least several hours, so would be fast to render. They would include a publicly usable "refetch content from the wiki" button (detailed placement, wording and design to follow) so that if the source page was spammed anyone could fix it on the wiki then clear the cache. If abuse became a problem we could easily "protect" those pages.
