Does anyone know what the most broadly implemented standard is for signalling that a web page has an alternative ActivityPub endpoint?
What I found online (and with @evan@cosocial.ca and @silverpill@mitra.social’s input) was to deliver a Link header and set a <link> tag, but it doesn’t seem to work (at least with Megalodon)…
@julian @silverpill no recos for consumers yet, but: I’d start with content negotiation, then Link headers. From there, fallback to <link> elements in HTML. Last recourse, try Webfinger, especially for non-HTML resources like images.
