I'll note that, even if it's done manually, my original post and the copied thread on Twitter (with comments!!) are a reasonably good example of how presenters at PressEd could both give and archive their talks on their own websites.

As a quick sketch, I'm using fragmentions for highlighting/targeting particular segments, and I have both Webmentions and Semantic Linkbacks plugins in combination with a free Brid.gy account to get the comments to come back to my website from Twitter. All of the syndication could be done relatively quickly and manually otherwise.

I've also thought about starting a conversation with an initial post and then continuing the presentation throughout the comments section, for which I've previously documented a bit about how to manage threaded conversations between my website and Twitter.
