We are Pinterest fanatics and we know that many of you are too, but if you have yet to join the pinning frenzy, what are you waiting for? Pinterest has made some huge changes in the last week that make it even easier for you to come pin with us. First, they went and announced open registration—no longer do you have to wait for an invitation! Then, they announced the launch of two new apps: an iPad app and an Android app. And if you are an iPhone owner, you can download a freshly-updated copy of the iPhone app. So what are you waiting for? Click on over to Pinterest.com to download the apps you need and make sure you say hi to Mama’s A Rolling Stone while you’re there.
