1/ Re #webmentions, this post by @robb points out that 3 of the webmention types covered by Bridgy/webmention.io are essentially "Mastodon webmentions": like-of, report-of, in-reply-to. Those seem to be the most useful webmentions to include at the bottom of each Cybercultural post, as they (hopefully) encourage readers to talk about the post on Mastodon...or at the very least, to join Mastodon and follow me (or a commenter) there. https://rknight.me/blog/what-even-is-a-webmention/
