tantek_ !tell aaronpk do you know if 1) you supported receiving webmentions as of when you posted this https://aaronparecki.com/2013/05/21/4/xkcd and 2) if you happened to have received barnaby's comment (or eschnou's) via webmention or pingback? (did you even support receiving comments via both back then?)
