@timbray I recently started an initiative to get web+ap (aka https://fedilinks.org/ by @SoniEx2) support in various apps. My plan is to get at least open and autolink (making the URIs clickable in plain text) support and if/when that has some adoption clients will have an easier time to generate and use those links too.
#Conversations_im has support for linking (including fallback). Fedilab has support for opening. There is an issue for Tusky (https://github.com/tuskyapp/Tusky/issues/5027)
Help me spread he word!
