Generally there's only 2 big problems for me:
- The lack of users and activity. Not so bad in tech-oriented areas but many niche places or places for "normal" people are barren.
- The homogeneity of the people here. People are generally speaking medium to heavily left-leaning, tech-oriented males of western Europe/US. I identify with that group too, but I wish there was more diversity and less "echo-chamber"-ish content. There is a lot of content that humiliates, jokes about or bashes the worst side of the right wing or laments non-techy people and that kind of thing. It gets a little tiring and I'm afraid it only serves to push that other demographic further away from the fediverse, while we should encourage everyone to use decentralized social media. I don't think it's great if the fediverse just becomes "social media but only for left-leaning tech people".
Still better than Reddit or Facebook 🤷
