It's amazing how frequently social sites change. Just after Facebook announced it would revamp Timeline, Pinterest announced that its new test page has gone gold.  The first users scheduled to receive the new page will have their profiles updated Monday. 

Unless you love Pinterest already, you may not notice these page updates immediately. The most striking change is that each pinned photo appears larger. But behind the standard Pinterest paintjob are major functionality improvements.

Now, whenever you hover over a pinned image, you’ll see a set of images from the user. You’ll have a recommendation feature, allowing you to rate pictures that appear on other people’s pinboards. And when you return to your own pinboard from your friend’s pinboard, you’ll automatically return to the exact spot you were looking at before you left the page.

Pinterest, as most of you know, is the fasting growing social network with an estimated one out of every five Internet users using it. We predict that these new changes will not help it grow significantly faster. They will, however, improve the user experience and keep Facebook or Google+ from entering into Pinterest’s market domain.
