I haven't been able to determine when the content was last updated, but some of the comments on the site are ~8 months old, so it might be a bit out of date.
That said, the basic concepts should be more-or-less unchanged.

Aside from not mentioning aggregations it should be fairly accurate, and is still a useful guide for a beginner.
I' hoping to revamp it to discuss aggregations over the next couple weeks.
I lost most of my disqus comments, unfortunately, when I relaunched the site last week as the URL structure changed. I revamped the book to have more content per page. It's probably a little less SEO friendly, but makes for a nicer reading experience.
I would really appreciate if you could put it back, it's really a good listen.
