Pinterest is where you can literally pin photos
of interest. You can create categories, ie: places,
food, events etc. You can follow people of interest
or they can follow you. Pinning can be from your 
computer, the web or other fellow pinners. People 
pin stuff from vacations to what you had for lunch. 
You can join Pinterest by going to Pinterest.com 
and request an invite. The addiction begins, happy
pinning everyone.
