proper viewpoint meta tag to make iphones work
replace getFeedItemMeasurements and isFeedItemVisible by something that actually WORKS

as it's no longer offsetted to the page top but rather the top of #feeditems
automatically load next elements when the feedmore comes into visibility while scrolling
fire a scroll event on feed item load, so that, if the feedmore is visible on loading a feed, automatically new items get loaded
