Indeed, blue titles evoke MS Word. As pointed out, a PDF rendered with this style would be great help in understanding it. Perhaps it's a good choice for on-screen reading, but shouldn't you go with serif typefaces when laying out for print?

A long time ago I did some googling (aka `research') on the subject and indeed I found out that using serif for printed documents is non negotiable ; it's supposed (and I agree with that) to let the eyes decrypt words faster and smoother than when reading sans serif. Oddly enough sans serif is easier to decipher on screens. I don't know yet which kind of fonts I should use on my e-reader though.

The web seems to think it's a matter of taste and adequacy nowadays:

Those studies focused on geometric sans serif fonts like Helvetica. Humanist sans fonts have been demonstrated to have higher legibility in print.
