Feynman Lectures on Physics Vol. 1 Released in HTML Format 129
Dr. Richard Feynman's lectures on physics have been iconic standards of physics education for the past five decades. Videos of the series were put online at Microsoft Research a few years ago, but now the entirety of Volume 1 is available over simple HTML (mirror). In a letter to members of the Feynman Lectures Forum, editor Mike Gottlieb said, "It was an idea conceived many years ago, when through FL website correspondence I became aware of the many eager young minds who could benefit from reading FLP, who want to read it, but for economic or other reasons have no access to it, while at the same time I was becoming aware of the growing popularity of horrid scanned copies of old editions of FLP circulating on file-sharing and torrent websites. A free high-quality online edition was my proposed solution to both problems. All concerned agreed on the potential pedagogical benefits, but also had to be convinced that book sales would not be harmed. The conversion from LaTeX to HTML was expensive: we raised considerable funds, but ran out before finishing Volumes II and III, so we are only posting Volume I initially. (I am working on finishing Volumes II and III myself, as time permits, and will start posting chapters in the not-too-distant future, if all goes as planned.)"

Feynman was known for his contributions to physics, for communicating concepts clearly and in an interesting manner, as exhibiting certain traits known as "being human".
Now there are physicists who did far better in each of the three areas than he did, but very few (if any) did as well as he did in all three areas.

Nah, that's Einstein. He got lucky once and stole Olinto De Pretto's formula, but after that? Feynman was working all the time.
De Pretto figured out (or perhaps made a lucky guess) based on his understanding of the lumineferous aether. Einstein derived it from his special theory of relativity. Einstein presented E=mc^2 in a followup letter to his paper "On the Electrodynamics of Moving Bodies" (i.e. it's an interesting derivation, not an essential part of the theory). There was also the photoelectric effect and general relativity. Of the three, special relativity is arguably his least impressive work (Lorentz, et al, were also working towards it).

The TeX source for the equations is just embedded in the text of the page. The use Javascript to render them. I'm not sure why that was expensive.

No. Not over-rated. He was capable of communicating ideas, deep and otherwise, clearly, which is very difficult. Consider how to convey the difference in magnitude between gravity and the electromagnetic force. The example he gives goes something like this:
RF: What is your charge right now?
Student: neutral.
RF: Why?
Student: Because we have the same amount of positive and negative charge.
RF: OK. What would happen if you took some electrons from your neighbour?
Student: I would become positive and he would be negative
RF: Yes. Now I want you to imagine you steal some of the electrons from your neighbor. Let's not be greedy. Let's say you take 10% of them. Now you are negative and your friend is positive and you will feel an attractive force towards him. The question is: how strong is the force of attraction. Is it larger or smaller than the weight of the Empire State Building?
Student: Hmmmm...dunno. I'm gonna guess larger.
RF: Yes it is larger. But how much larger. Is the force of attraction between you and your neighbor larger or smaller than the weight of Mount Everest?
Student: I'm gonna go with larger.
RF: Yes, you are correct. In fact, the force of attaction between you and your neighbor WILL BE ABOUT THE SAME AS THE WEIGHT OF THE ENTIRE EARTH!
The above paraphrased lesson emphasizes like nothing I've ever heard before how weak gravity is and how strong the electromagnetic force is. Simply brilliant.

Bruce Sherwood, who taught a course using the Feynman Lectures as a textbook, has some interesting comments, saying that it went quite well for him.
