Maybe we can discuss and come up with something similar to the small votes we give to comments. There are some meme compilation posts we curate now and then specific to certain communities in our incubation but they are very few.
I wouldn't mind giving it a try, will have to check your community activity a bit more first and maybe a trial run to see how it evolves.
I mainly post in the memehive community and I think @holovision takes care of it :) As far as I know there are no other active meme communities
