I've updated (and un-gemified) the planet.rb quick starter script v1.0 
that lets you (auto-)add articles & blog posts to your static (jekyll
& friends) website via feeds (and planet pluto).
Happy planet! Prosit 2020!
PS: You can find a live sample "Planet Ruby" website built with
the planet.rb quick starter script (and jekyll / github pages) online .
For a great real-world example / setup see the "Planet OpenSUSE - Linux OS" .
