So the bottom of the linked article says 2016, which made me immediately think 'old!'
It makes complete sense for the manifesto to be timestamped, but the surprise was that I didn't realise I was reading the manifesto rather than this actually being the normal landing page... there's no title or anything and HN usually links to homepages.
But a quick glance at the forum and the homepage shows there's activity there still!
Clicking around, this seems really interesting :)
