Commenting here on your Known install to see what happens... I am trying both Known and Wordpress with Indieweb plugins: https://andreaaarbogst.com = WP, https://andreaarbogast.com/stream = Known. With WP, having lots of issues getting Bridgy to parse my webmentions. After several hours, got it to pull them in by switching to 2016 theme, but they are still not right, see: https://andreaarbogast.com/2017/11/28/16040/#comments. Links go to bridgy.appspot.com rather than FB. (Facebook is important for me, despite my general dislike of it, because I am active in a dog sports community that uses it extensively). With Known, I am not liking the way it displays my twitter likes-- would like the twitter embed to be shown, but I don't have the chops to make that change.
