Nothing has replaced what Reddit was. I use Lemmy for the nostalgic feeling but it does not compare.
I followed news, politics and science, mostly. The community on Reddit used every tool available to create credibility. Then profiteering tore it asunder.
The only other social media app I ever use is Facebook. But it’s purely for connections to friends, family and local hobby groups.
I agree. Slotted screws are the worst.
