The Nib? WTF is that?

So some of my favorite content creators have started posting comics to The Nib and honestly I'm really confused.  The about page doesn't help illuminate anything for me, but after doing some more digging it looks like it's a site that is using a new platform called Medium.  Thanks to Wikipedia I've learned it's a blog-publishing platform, but because it's 2015 I had to go to Wikipedia to figure it out because nothing is spelled out in clear language anymore, so their About page is all vague marketing-speak.  Anyways it might be worth your time to check out The Nib for some comic goodness.
