@chrismessina Some standard like https://github.com/fedidcg/FedCM could maybe be more appropriate, and eg. reviving some of the original Web Intent work by @paul to move beyond the Web Share API into supporting actions as well (also explored by https://indieweb.org/webactions)
At its core Mastodon is basically ActivityPub + WebFinger as far as I understand and eg. WebFinger can be reused by others, as can ActivityPub, and granular open specs is what push us forward? DiSo-style, right?
