We’re told that services like Findings and Readmill “make reading social.” Both sites encourage members to post quotations from what they’re reading to share with other members. They’re similar in purpose, though Readmill places its chief emphasis on books — and is heavily invested in the iPad as a reading platform — while Findings feels more browser-centric and encourages its users to clip from online text of all kinds. So do these sites “make reading social”? Well, it depends on what you mean by “reading” and what you mean by “social.”
