But I accidentally caused the URL to be "list-of-lists-1", because I originally relabelled List of Links to List of Lists but then changed my mind.
Btw, I notice the absence of a tag for lists (e.g. lists of advice that don't link to anywhere and aren't repositories designed to elicit advice from the comment section).
See also my other comment on all this list-related tag business. Linking it here in case you (the reader) is about to try to refactor stuff, and seeing this comment could potentially save you some time.
I was going to agree, but now I think it should just be split...
The Resource tag can include links to single resources, or be a single resource (like a glossary).
The Collections tag can include posts in which the author provides a list (e.g. bullet-points of writing advice), or links to a list.
The Repository tag seems like it ought to be merged with Collections, but it carves up a specific tradition of posts on LessWrong. Specifically posts which elicit topical resources from user comments (e.g. best textbooks).
The List of Links tag is usefwl for getting a higher-level overview of something, because it doesn't include posts which only point to a single resource.
The List of Lists tag is usefwl for getting a higher-level overview of everything above. Also, I suggest every list-related tag should link to the List of Lists tag in the description. That way, you don't have to link all those tags to each other (which would be annoying to update if anything changes).
I think the strongest case for merging is {List of Links, Collections} → {List}, since I'm not sure there needs to be separate categories for internal lists vs external lists, and lists of links vs lists of other things.
I have not thought this through sufficiently to recommend this without checking first. If I were to decide whether to make this change, I would think on it more.
I created this because I wanted to find a way to unite {List of Links, Collections and Resources, Repository, List of Related Sites, List of Blogs, List of Podcasts, Programming Resources} without linking each of those items to each other (which, in the absence of transclusions, also means you would have to update each link separately every time you added a new related list of lists).
