I love Pinterest. It is THE social media for visual communication, IMO. Pinterest is a great place to do accelerated research of art images, as well as a great place to post images of your own art. During my first week on Pinterest I found amazing art images, had hundreds of my pins repinned, received lots of comments, and made new connections with a museum curator and several artists.
By clicking on images I like on Pinterest, I find interesting blogs and websites. Today, I found a wordpress blog called Art Snapper. Art Snapper accepts submissions of images. Artists, rather than submit your own artwork images to Art Snapper, you could cross-promote by asking a friend to submit an image of your art, and you submit an image of their artwork in return. Art Snapper posts your art images to their blog and to Pinterest where others pin them to their boards, *like* your image, and follow your link back to your website.
Last month, Pinterest drove more traffic to websites than Twitter, and Pinterest drives more traffic than Google+, YouTube, and LinkedIn and combined .
