Pinterest gains as a concept
Pinterest has already become much more than just a pretty face. The commerce traffic that it drives continues to amaze. This week Shareaholic published a study claiming that Pinterest created more referral traffic than Twitter did in February.
Pinterest is becoming something of a test case in the 'web-site vs open platform' argument in social media. It is relatively closed off by not having a strong API like the other networks have. One possible result is that a number of sites and apps are emerging that borrow the concept of pinning and in a sense they compete with Pinterest rather than embedding it into their systems via an API.
Some examples that have been talked about just this week: Friendsheet, a Facebook app, has been described as 'a Pinterest clone' that adds similar functionality to the world's largest social network. TheComplete.me is the Pinterest for dating, travelers can pin their plans on Wanderfly.
Then of course there is Fancy, which some people feel is an even more merchant friendly option for the visually inclined.
