[[plugins|plugin]] to implement pingbacks would be great.

+Happy 9th anniversary, bug!
+
+For whatever reason I was compelled to look at this situation afresh. I've
+added some instrumentation to my own site to see whether there's any external
+attempts to issue pingbacks to my own site, to gauge whether it's worthwhile
+spending any more time on this. But it looks like pingback in the wider world
+might be dead or dying.
+
+[I started a conversation on Twitter with the inventor of Pingback to see what
+he thought](https://twitter.com/jmtd/status/1042730998839107585). He suggested
+taking a look at "webmentions". here's some preliminary reading on those:
+
+ * <https://indieweb.org/Webmention>
+ * <https://kryogenix.org/days/2014/11/29/enabling-webmentions/>
+ * <https://www.kryogenix.org/days/2014/11/30/vouching-for-webmentions-hashing-for-vouches/>
+
+At this point I don't know if webmentions actually has more traction than pingback,
+but the key issue I guess is whether it's growing. I'm going to (but am yet to) add
+corresponding instrumentation to my site to try and track that, too.
