Besides Facebook, which I think is all of our favorite site, Pinterest is also one of my favorite sites. I enjoy it because you can literally find just about anything on this site. I enjoy looking through the art section because is inspiring and also has many examples of good (and bad) design. It is almost like a text book for design with many examples of all kinds of design. I think it is very functional and useful in saving things you are interested in. I like that you can pin things to your own boards in categories so they are easy to find when you want to refer back to them. I always find my self looking at interesting art, clothes, makeup, or anything really online. The things I like i usually copy and paste to a sticky note or something on my computer but never remember to refer back to it or can not find it. Pinterest makes it easy to look back at what I found interesting or enjoyable.
