I mean, you do you, but I don't see any of the things that you want requiring active surveillance. That all seems very attainable by having decent search, filtering and categorization tools.

If anything, I find myself now seeking "hidden gems on Steam" despite Steam knowing everything about my gaming habits. And that's on Steam, which does have a semi-decent crowdsourced tagging and categorization system. Their main page recommendations for e have consistently been either generically popular shovelware or insistent recommendations for games I do like but already own in other platforms that I can't tell Steam to stop shoving down my throat.
