I feel like most users have switched back to Reddit, but I’d like to have an alternative to Reddit.
I might post memes here but I don’t want to keep this active by myself.
This is also a common issue within lemmy, and I did try to revive 2 other communities, but one barely succeded while the other just didn’t see much new posts.
I run a small discord server which has about 200 ppl and it’s fairly active (few messages per day), but that’s a different format/platform
As for getting new members on here, try asking the mods of those communities for a collab or affiliation or something
