Unasked-for meta complaint about the site, not the article itself:

I hate that thing where you visit a blog post (judging from the URL) yet the blog post is seemingly endless (judging from the scrollbar), and when you scroll down you hop into the next blog post (URL just changes).

The scrollbar is useless in that case, I can't gauge the real length of the article. The Gates Foundation has more money than God, maybe spend a tiny little bit of it on a good UI designer, yeah?
