@dangoodin There is a lot of discussion off-Masto and -Fedi about why QTs/QPs and search work (or don't) the way they do here. But in summary:
QPs *can* be used for good, but arguably are overwhelmingly used for toxic behavior—dunking, harassment, mob mentality, etc. A lot of this comes from people—especially the marginalized—who've been victims of this toxicity.
Search, basically the same deal. Tags are a great way to find content you want and opt-in to promote your own.
@chartier Those rationales may or may not make sense, but in either case they are dealbreakers that will prevent Mastodon from ever gaining critical mass. Until those features are available, Mastodon will remain a fringe social media outlet.
