I left X because of how bad it got but BlueSky is also quite often useless in terms of good discussion. Recently any substack article posted is just filled with comments about how using substack supports Nazi ideology, no other discussion to be had. When it comes to anything related to AI the comments are all about stealing from artists. It is as if people just wait for the right buzzword to appear and post their canned response. Interesting posts that don't cause any controversy just don't have much engagement.
