I think it's audience-dependent. For readers with less background and less pre-existing motivation to learn the material, I think it helps to cut down on the density a little. It's kind of a cruddy experience to have to pause and digest every sentence as you go and it makes it physically hard to read a book that way since you have to constantly track where you were.

If the audience has more background in the material and a stronger pre-existing motivation to read it, then it is probably a distraction, and they need a higher density of information to keep flow.

So true.

Especially with term highlighting, makes it 2x easier to read and keep the information flow to process (and funnier?).
