It’s probably redundant to test HTML structure for my pages, but what the heck.
There’s no rule, but obviously every webmention to my site will have full author info including photo.
Look honey I added Webmentions to my Datasette dashboard!
Sweet, jmac liked my mention! Wait why are tests failing? Maybe check the dashboard?
I fixed it!
The fix is reasonable defaults for response author info. I got other fixes in mind, including a default "card" for anonymous response authors. Also, inferring author info from source site. Thanks for the help and the ideas, jmac!
