With the blossoming popularity of sites like Pintrest and Clipix, the question arises - should I pin or not? Given the issue surrounding who owns what you're pinning and these services Terms of Service I think you should look before you leap.
In the past few weeks there has been much written about Pintrest's TOS in regard to their indemnification of copyright and their rights to use what you pin. Here are some articles I suggest you read before making that decision:
Pintrest's TOS: http://pinterest.com/about/terms/
Clipix's TOS: http://www.clipix.com/TermsConditions.aspx
It will be interesting to see if Pintrest and/or Clipix change their TOS in any appreciable way. I like that Clipix would allow for private as well as public boards, but their TOS is just about as egregious as Pintrest's. I'm not willing to assign away the rights of the images/content to someone else, and even with permission to post a photo from a designer or vendor, I don't have the ability to assign their rights away, nor would I want to.
Until it's clear how as a shopowner, I can use these services and honor the Intellectual Property of both the designers and myself, I'm holding off using either service. Hopefully the way will become clear in the next few months to make it something that is not only useful and fun, but honorable.
