That's a really good question: where to stop.

Would it be possible to filter them by type? Put them all on the site, tag them, and let people choose to display particular tags or categories.

100% possible! There's still the question of whether you'd put them on the existing site, or make a new (more general) site to host all the links on. Definitely keen for thoughts as I'm torn between the two

There are Unix programs where a single executable answers to different names, and behaves accordingly (e.g. busybox works as ls or cat or ..., I think).

You could have a single site, with different names, where the filter is preset by the URL used.

Personally, I think I'd keep them on the same site and have checkboxes on the left hand side that could be checked or unchecked for particular categories. (Sort of like how a lot of mapping software works.)
