@kylewm RE: Archaeology - This was actually the _easy_ part and is one of the greatest values of webmentions in general: once I'd found/seen the original post, having access to all the comments & mentions of that post in social media and other locations actually made it a no-brainer to find the conversation with the solution! (Though I do notice that there's a display issue on that original post with how my more recent webmentions from Known are showing up -- but that's another problem altogether.)
