Mine are some of the communities I have created:
!artbykids@lemmy.world - Community to share artwork created by kids. Anything creative is considered an artwork.
!alternateuniverse@lemmy.world - Improv community where anything and everything can happen. It's all true. Continue the conversation.
!in100words@lemmy.world - Answer any question/prompt in exactly 100 words. Your answer can be a rant, story, poem, essay, advice, instructions, anything, as long as it is exactly 100 words.
What are your favorite communities needing some activity? May be we can all find some new favorite communities to grow.
!internetfuneral@lemmy.world really speaks to me in a way that other meme subs do not. Also not all memes, sometimes just images that are a mood. Currently a sub that is largely carried by one poster (though they're far from the only person posting), so it could use some more love
Yeah I love some of the posts there. I just can't put my finger on what exactly would fit the community.
