@julian IMO there's no reason why a web browser should understand where to open fedi links, without having any other type of app properly address those links as well.
What if someone in an instant messenger or email app sends you a link to fedi content?
Defining it at the system level (again, as is done with email) removes critical uncertainties.
Fedi has other big UX issues as well. Celebrities don't like it here because the TL mechanics make them unintentionally annoying... users follow then later mute them because their posts are popular for a while and we have to see them each and every time they're boosted (or manually silence those posts). Allowing the selection of some transparent algorithms could fix this.
