The bad news is that most of the Slate series is still not functioning properly (grrrrr); the good news is that I've been given permission to republish the entire series here on this blog.
The first Slate article is, for the most part, fine (some of the photo links are a bit wonky, but it's mostly OK), so you can read that on Slate. You're better off reading the second, third, fourth, and fifth articles here. The photo interface here on the blog isn't as elegant as the one on Slate, but at least all the links work, all of the text is present and accounted for, and so on.
So if you want to take in the entire series, or pick up where you left off, here you go:
More developments soon.
