Damn, I just realized, that I wanted to post the original article, not the mention on 'erlangcentral'. But editing URLs is not permitted, so, for everyone interested: http://inaka.net/blog/2016/08/17/why-json/
That's handy, since in the OP the link to the actual description of the format is broken due to some frame-madness.
Mods: please swap the URL. Thanks.
I can't see any reason not to submit the original link as a new item.
