You can add them to any community :) I added a low volume feed to !medicine@lemmy.ca as a test, and you can see the recent post it made
You can also chain multiple commands in one message iirc
I’m looking around for other feeds that don’t have too much spam. Some ideas include
- updates on new releases for FOSS projects
- the patients feed for !marinemammalrescue@lemmy.ca, but the feed itself is down currently
Not sure how rare they are, but it was rare for me
