digital magazines need to stop trying to act like magazines...

Subtraction.com: My iPad Magazine Stand:

as a content experience, [reading the New Yorker through the ipad app] was an impediment to my normal content consumption habits. I couldn’t email, blog, tweet or quote from the app, to say nothing of linking away to other sources — for magazine apps like these, the world outside is just a rumor to be denied.

What digital mags could provide is a "citation" mode - the ability to select text, "cut" it, and have it automatically append to that the bibliographical/footnote citation to it so that the person doing the excerpt doesn't have to remember the terse syntax for magazine citations these days.

Citations are a selling point, and magazines should encourage them, not restrict them.
