With the new Community Ads system for 2021, we now have the ability to choose specific questions on SFF.SE (no need to make custom images for them) and get them promoted in the sidebar or topbar of other SE sites. Obviously this is a nice opportunity to get some of our best content out there for more eyeballs, but we need to get a good list of stuff to promote. This is hard to coordinate via the above-linked meta posts, since answers there are required to be in a specific format with one proposal per answer, and it was getting messy to discuss via chat. So here's a new meta post specifically to gather nice SFF questions to promote on other sites.
Near neighbour sites with scope overlap (here we should try to choose SFF questions to promote so that they can't say "eh, that question could be asked on our site, why point to another site for it?"):
- Movies & TV
- Anime & Manga
- Role-Playing Games
Other sites that might be interested in specific parts of our content:
- Artificial Intelligence
- Space Exploration
- Arts & Crafts
Probably many others, these are just a few examples to bear in mind.
I'm making this post community wiki, so that it can have just one answer which can also be community wiki, and everyone can edit freely. Let's divide the answer into sections by site, and then in each section we can list/edit/add/remove some questions until we find a nice candidate to promote on one specific SE site.
