As a man whose started 7 different communities I'd like to defend those people saying, if you don't immediately get a good response it starts feeling like screaming into the void.
I started a meme community !aneurysmposting@sopuli.xyz and it immediately took off and is doing well. On the other hand other my worst community got 2-3 people making one or two comments after a month of 2 posts everyday.
Meme communities do well. Niche communities require lots of people finding it and being active.
