Webmentions in and out!
Yes, apparently I made it! I'm able to receive webmentions, thanks to the service created by Pelle Wesseman at webmention.herokuapp.com. And I am also able to send webmentions through the Ruby code created by Aaron Parecki. The code surely fires out webmentions, but I didn't see any on the mentioned posts (yet). Hmmm... :/
New service: WebMentions for static pages
Want to implement webmentions but you’re using static pages a-la Jekyll? No problem. Pelle’s got you covered.
