I do have to admit I'm part of the problem...! I think that this probably is the reason why meme communities on Lemmy are so big right now -- memes are designed to be reposted, so we're seeing a lot of that content opposed to original content (which isn't a bad thing, but it tends to drown out other content on All pages). Maybe I can get around to making more art for once and I can start to populate Lemmy with more content :)
But for right now, I agree that things are quite fine as they are. I don't really feel a need to create a separate community as I would on say, another larger platform, because right now this space (and others on the Fediverse) feels like a community where people's voices are actually heard. It's really refreshing, honestly. But yeah, it's nice to see what people think on this! Thanks for your input!
pict-rs, the software Lemmy uses to upload media by default, is a bit wack right now so people usually get around this (and some other issues) by uploading to sites like files.catbox.moe or postimages.org (the former of which can upload any media while the latter can only do images/gifs). I recommend checking that out - it can come in handy sometimes!
