Of all the first world problems that rattle our sensitive, effete internet brains each day, having to click between pages in a long article ranks high. It's eats up time! And Google agrees—so it's serving up one-page views.
Google gets the tedium of multi-page navigation—which also make good reads harder or impossible to Instapper—so it's now automatically pointing you to a full view, when available. If not, you'll be stuck with the regular paginated text. This will probably piss off some publishers, who rely on pages to grind extra clicks and ad views from their stuff, but, hey whatever, bean counters. [Google via Silicon Filter]
