Yesterday I published a fediverse-aware / indieweb-aware version of a "share to..." / AddThis-like tool. It allows you to easily add a “share to ..” button to your website that works with as many social platforms as possible, and attempts to use whatever share intent a platform might have available.

One of the things it does is look for HTML header metadata like <link rel="share-url" href="https://werd.io/share/?text={text}"> in order to figure out how to share to a given platform.

It was a first draft, and I'd like to socialize that idea — what should it look like to advertise a share intent on a platform using microformats?

There was an attempt over a decade ago called OExchange, which used data stored in .well-known. I'm okay with supporting it, but it never took off, and I feel like something simpler would be more effective.
