Side note: I'm struggling to read these articles with the very thin font used (on MacOS). Using font-weight: 300 with Helvetica Neue is a strange choice that I'm seeing in more and more blogs. Maybe it looks more readable with other OS fonts and is just an oversight.<p>Bumping it up to 400 in dev tools makes is far more readable.
