Well I don't know if Pinerest is going to really be the NEXT big think, but there is a lot of buzz around it, so I signed up for it. Wouldn't you know that my name is already taken. (One of the reasons to sign up early on these kinds of social networks) So here is the HTML address I ended up with http://pinterest.com/bradfordsmith13.
After you look through my stuff and move onto the sea of pictorial rabbit holes known as Pinterest, you will loose hours of your life looking at all the wonderful pictures that people have pinned.
As for weather Pinterest is a useful site and not just a time suck, I haven't decided yet. I have seen lots of wonderful art that is of a much higher quality than what I have found on Flicker.
The original Pinterest idea was that people would pin images that would link back to the original web site. I have found some new artists websites already. But! A good portion of the images have been detached from their original source, so they now float around the Pinterest sea being pinned over and over without the artist getting any credit or recognition.
