Have you checked out Mastodon? Idk if it’s exactly what you are looking for since it’s more akin to Twitter but it has hashtags that you can pin to keep up on. There’s some stuff that’s more longform and visual on there too or at least people will link to there stuff if it isn’t listed there. Maybe try a couple different apps, I use megalodon, see if does what you need.
Life is a marathon not a sprint. We don’t all have the same problems and we don’t all have the same tools at same time to deal with them and that’s ok. The value of you is so much more than just the accolades you receive or the money you earn. The meaning to your life is whatever you decide that meaning is not whatever is forced upon you. Remember to be kind to yourself. All anyone can do is try and be a lil better than the day before.
