Pinterest is one of the fastest growing social networks of late – the visual style of sharing content has made it hugely popular with anyone planning a wedding, having a baby, baking cupcakes, planning an overseas trip or decorating a house. You get the idea.

One of the most popular requests has been for private boards. Sometimes you want to pin a few ideas to bookmark them for later – without having the world know. I’m sure I am not the only person to notice a friend pin a few baby pins and wonder if there was some news to come! Up to now it was not possible to have a separate private area, until last week when Pinterest has introduced 3 secret boards per Pinterest account. Perfect if you are planning a surprise party, or are expecting a baby but haven’t told the world yet. Or if you like weird stuff that you know no-one else will appreciate.

You can share your secret board with other selected Pinterest users, and they can also add to the board. If at some point in the future you want to change the board to public you can. And if you’ve been contributing to a secret board that is subsequently made public, you can choose to remove your pins. Note – you can’t make an existing public board secret (it’s a one way street apparently).

Pins, Repins or Likes on the secret board won’t show on your Pinterest activity log. They wont show in your Following Newsfeed either which is a bit of a drawback – to see new pins to your secret board you need to go to your Pinterest profile and scroll down to the bottom of your page.

You can add pins to your secret board via the web, iPad or mobile (Android/iPhone) apps.

This is a welcome addition to the Pinterest feature set, but I can’t really see a good reason to limit it to just 3 per user. Don’t panic though – if you are a contributor to a secret board then this does not count as one of your allocated 3 boards. This should see an increase in Pinterest activity as it was the most requested feature, however having to check the Pinterest profile page to see new pins or activity on the board will become a bit of a drag after a while as it is not part of the natural customer journey.

This feature is being rollout out progressively to users, so check your Pinterest page now! More info is on the Pinterest Support page here.
