Chemistry was dragged, kicking and screaming, into the Internet Age. The field is still a laggard. As evidence, consider the aversion of chemists as a group to preprint servers and their over-reliance on paywalled journals with hypervigilant exclusivity policies.
Glad to see Molecule of the Month hasn't changed style in many years.
As an aside, I wholeheartedly recommend the book "The Machinery of Life" by David Goodsell, the author of that site. The illustrations in the book have the same style as the site I linked, and have the important feature, IMO, of having a consistent scale throughout the book, which helps put a lot of the molecules in a more understandable context.
 IIRC it was two distinct scales, but still, it was a nice touch
Note: I helped develop PQR.
