Polyvore is an example of social shopping. Think paperdolls for your computer. It is free and easy to sign up. Software loads easily and quickly and enables you to begin to gather images to create collages (mashups to the uninitiated). Here is a brief tour.
Polyvore's social community focuses on fashion and interior design. Active Polyvore members range from design students, small boutique owners, professional stylists and the general shopping public.
Sets (or mashups or styleboards) can then be shared by embedding them into your blog with an embed code, shared via Facebook application or email.
