Instapaper

Instapaper facilitates easy reading of long text content. We discover web content throughout the day, and sometimes, we don’t have time to read long articles right when we find them. Instapaper allows you to easily save them for later, when you do have time, so you don’t just forget about them or skim through them. More info at http://www.instapaper.com/faq
