Hi!
In the Apollo app (basically the reason i started using reddit and the reason i also left reddit lol) there was a very useful feature: friends.
It was not a mutual friendlist like facebook, and not even much of a follow like twitter; it was more a ‘‘favorite users’’ list.
Basically I added in there people that always commented stuff I was interested in and this helped me find new communities and interesting post without relying on other discovery ways. Seen the decentralized nature of lemmy, i think it could be even more useful than on reddit.
I don’t know if this is helpful or not, but you can do this on Sync for Lemmy. As a test, I just added you as a favourite and now you appear in my Favs list alongside my chosen top communities.
However I don’t know if there’s any way to create a feed consisting of all favourited people’s posts, which would be more useful IMO than having to check each individual favourited person. Will have a go and see if I can find a way.
EDIT: Couldn’t see a way to do it unfortunately, but have started a thread on the Sync community to see if anyone knows how.
