If you have not tried Pinterest yet, at least watch this video and see what the fuss is about. When you actually start using Pinterest I have to warn you: you might get seriously addicted to it. I know some people who will come close to having an anxiety attack if they cannot get on Pinterest.
So why get left out. Give it a try. And if you own a business selling products you SHOULD be using Pinterest. you are definitely missing out on sales if not.
