I am a big fan of Pinterest. I use it both personally and professionally. I use it to connect with co-workers and also to get ideas for a variety of purposes.
I had been using Pinterest for my personal use but after taking a professional course I started a Pinterest account for our teachers. We all add to the boards and use it as a way to collaborate. It's been a great tool for our staff.
Love to use Pinterest! I did use this with my Foods 3 class this year. They set up their own accounts and we used it for their recipe file project. It worked great!
