Issuu recently launched "Clip", a feature that lets users grab snippets from any Issuu published magazine, add a comment and share the Clip via social networks. While some think this is making leaps and bounds for the company and their users, it made me consider the implications for digital publishing, ownership and free content.

On the one hand, you could argue that if features like Clip became popular and eventually rolled out to paid or membership publications, it could affect sales. Why would readers pay for a digital edition or a subscription when they can find the best bits on pinterest and twitter?
