@aaronpk @indiescripter Another option to encourage others to post their replies on their own sites rather than directly on yours, you could provide a URL box and details for people to webmention you indirectly (especially if they don't support Webmention yet). See the comment section at the bottom of http://boffosocko.com/2016/12/28/homebrew-website-club-los-angeles-notes-december-28-2016/ for an example or see https://github.com/pfefferle/wordpress-webmention-form for some sample code. I think I've yet to have someone take advantage of the option, but my IndieWeb heart feels warm for providing it as an encouraging option.
