This was interesting :- ) Doesn't seem to work so well with Facebook to me? If I write a blog post and use Brid.gy: I'm getting the impression Brid.gy (https://brid.gy/ https://brid.gy/) only lets me see [mentions about the blog post] that my Facebook account can see? If there's a public discussion about the blog post, somewhere at Facebook in a group of people I'm not connected with — then Brid.gy won't find it? Is that how it works in general? I mean, the blog & web-mentions tech, will find web-mentions, only about things the blog author can see, via his/her own social media accounts? I'm then getting the feeling that ... if a blog gets popular, shared and discussed a lot at Facebook etc, 99% of all discussions & shares etc, won't be found, because the blog author isn't connected to those people on the relevant social media places.
