I am the creator of https://comments.network/ which
    you are using on the bottom of the article, and it's
    the first time I spot it in the wild!

That's pretty cool! I made my own version of this a few years ago, and if anyone is interested it's open source: https://github.com/jeffkaufman/webscripts/blob/master/commen...

(Mine can also do facebook and google plus, though to do facebook it needs an API key.)
