Pinterest opens up registration for all

Pinterest, the social network that allows you to "pin" photos and have others comment on them, has opened up registration to all users. Previously the network was available by invite only, but starting from today anyone on the internet will be able to freely sign up for the service. Users can sign up using either their Facebook or Twitter logins, or they can simply use an email address.

The social network has gained some momentum over the past several months, giving users a more visual way to share their finds among friends. The timing of the open registration is interesting given recent rumors that Apple is eyeing up a purchase of The Fancy, a service not too far removed from Pinterest.

Pinterest's valuation has also soared over the past few months. Earlier this year, the social network was valued at around $1 billion, and more recently Japanese conglomerate Rakuten valued the company at around $1.5 billion after a $100 million round of funding. Rakuten has multiple ecommerce sites scattered around the internet, and the inclusion of the "Pin It" badge on any one of them will be sure to further raise the profile of Pinterest.

Still, if you're not too fussed about the business side of things and just want to share content with your friends, Pinterest isn't a bad way to go about it. Head on over to the website to sign up with your Twitter, Facebook, or email if you haven't done so already.
