Red hot social network Pinterest has just opened registration to the public after two years of requiring an invite to join. Anyone can now sign up with Twitter, Facebook, or just an email address according to a blog announcement.

“We’re really excited to have the capacity to offer Pinterest to more people and if you’re a Pinner with friends who’ve been waiting on the sidelines, we hope you’ll let them know. Happy pinning to everyone!” says the blog posts.

The move to go fully open is likely to accelerate the number of visitors to the highly popular social network whose popularity has surged over the last year. Pinterest is the third most visited social network in the US behind Facebook and Twitter.
