What is Pinterest? TechCrunch describes it as a “self-expression engine” along the lines of Twitter and Facebook. Users can create virtual “mood boards” or “vision boards" on which they can collect images. Users can create separate boards for any kind of interest--fashion, art, books, decor, crafts, recipes, workout ideas, inspirational quotes--and “pin” to those boards images that reflect their style and tastes. The community now includes over 1.5 million actives users (the majority of whom are women).
