I think most librarians will have encountered the following kind of pages, which are difficult to find a keyword for:

• Online social community stuff: it is not really "online go" and it is not properly "clubs and places" either. I've used both keywords for such pages, never entirely satisfied.
• Behavioral advice: typically all bad habits and the likes of those. We have no keyword for them, but I never really bothered to ask for one, because "advice" would be too broad a keyword and "habits" too narrow.
