I take the occasional peek to see if it imploded yet. I do miss certain communities. Only last week I was looking for some info on a historical subject. Google turned up nothing so I wanted to r/askHistorians. I hate they decided to stay on reddit and don’t switch to lemmy.
Personally I don’t think there is a one-size-fits-all solution. Each problem needs a different approach. We need to figure out how to have all these systems work in tandem.
