It seems like any platform that features link aggregation is soon overrun by bots and self-promoters trying to drive traffic, and pages and pages of link posts versus pages and pages of people talking.
Are there any lemmy instances or other defederated networks that focus on Q&A, niche communities, and people conversing, instead?
For hobbies, depends, but there is the general pinned post in !knitting@lemmy.world which list a lot of crafting communities: https://discuss.tchncs.de/post/842186
For parenting: !parenting@lemmy.world
Politics, you should be able to find a lot by searching that word into https://lemmyverse.net/
Finance? !finance@lemmy.ml
The thing is that people tend to post links as you can’t really force people to post if they don’t want to (or if they critical mass isn’t there). I’m guilty of that in the !parenting@lemmy.world for instance, as I don’t have kids yet, I can only but post articles.
Maybe the instance I’m on is wonky, because I can’t even find those communities - I just get the “top”/”default” type communities ala reddit: technology, news, etc, which are all linked mass media articles.
