OK: today you have met one. I have notifications turned on in desktop Safari for Facebook, Twitter, Slack, a handful of news sites that I like to keep up on, and probably some other stuff I am not remembering right now; and no: the idea of installing a native application for any of these services sickens me for numerous reasons (everything from concrete reasons of security and convenience to philosophical objections related to wanting to maintain an open, searchable, and hyperlinkable web).
