I think it's more annoying when the quote is (more or less) directly before the actual same text (like here). As such, it has no helpful function for the normal reader - it's only annoying (but might help the skim reader or rather only the "scroller" who doesn't really read). Whereas in magazines it was that you opened the page and looked at those few quotes and decided whether you wanted to read the text, in that way the quotes are not really annoying imo.
