Wow, Steward Langridge, inventor of the pingback mechanism, has enabled webmentions on his blog, as he tweeted just a couple of hours ago.

I think this is great signal for the webmention idea, and reminds me to keep on tweaking the webmention/indie web thing here in my blog, where I have the comfort of using a set of WordPress plugins that take care of the more complicated stuff that's going on in the background.
Steward in contrast uses a static site generator and seems to have found a way to integrate mentions in realtime with Javascript, and integrates them on (re)generation of his site's files. I remember that Aaron Parecki briefly mentioned in an exchange with Anselm Hannemann at the Border:None Creator unit that he's working on a solution for static sites -- seems that this is now working :)
