There's a bit of a spinoff topic here:
"With modern web browsers, there’s no need for explanations to follow the formats used in magazines, technical papers, and books. We can combine learning by reading, learning by watching, and learning by doing."
I DO believe there's a need for "magazines, technical papers, and books". I cut that quote pretty hard - I'm not sure if he's only talking about the "comp game" industry or going broader to "learning theory".
I'm moving into the topic that the types of info in a "manual" isn't the same info-theory-wise as all the stuff he was saying. We're skipping the DeadTreePaper vs PDF discussion here. Manuals are about telling you stuff like "Oh, yeah, right, this year you have to unclick the boxes 1,7 and 14 to get this year's return to file or it won't work at all, and if you miss boxes 13 and 14 it screws the client and you have no idea why at a ten second look".
So, we need manuals. Pop articles on the web don't cover that.
