Artstack
I am getting addicted to ArtStack. It is a great website for people who love art and love viewing and sharing all kinds of art. To join and start "stacking" just use my invite http://theartstack.com/users/signup/sharonerlichman and enjoy! Got this terrific website from Alyson B. Stanfield aka the Artbiz Coach. Check out her website as well--great marketing information for artists!
For more information on ArtStack and what it is trying to achieve you can read an article on it from the UK Guardian. "The elevator pitch is that ArtStack is a discovery tool with a social element – find a work of art that inspires you, 'stack' it to your personal art stack, which is a feed of your collected pieces, and share it with the wider community." Who knew it could be such fun discovering new works and artists. Sit down for a few minutes and time flies...
