You gotta make them.

For real, I love mastodon and its philosophy but sometimes I need some brainrot or something fun, and that site its only politics, tech, and memes made by old people

Tell me when you found some :‘D

maybe have a extra mastodon account where you just follow positive things and radically filter out negative stuff (even with word based filters)

and then i can just recommend:

• be patient. The awesome people will be found over time.
• lemmy communities are also great, but i dont remeber the names. But different instances have some funny meme communities.
• search hashtags
• in general explore stuff.

Mastodon seems to be in a weird middle that a lot of community platforms fall into. There are a lot of memes (way too many honestly) but they are political memes. I would imagine this is because a lot of people are genuinely worried about their future, but do not want to risk their life nor come off as "cringe".

This is not surprising, given that we are living in extraordinary times, but it is frustrating. I would like for intelligent and practical people to come together and talk about solutions - but we've generally been reactionary. You want good and spicy meem - but we've generally be reactionary. Like I said, its frustrating.
