gRegorLove cdevroe: I use the /posse-post-discovery method myself. E.g. https://gregorlove.com/2017/01/really-enjoying-the-group-of/ has the "Also on: Twitter" link with the u-syndication microformats. Bridgy periodically parses my feed and keeps track of that. And when that tweet gets a reply, it uses that to send the webmention to.
