Have you start pinning yet? Do you know your dip-died French braid from your red velvet whoopie pies? Once you join Pinterest you will. Then, like many addicted Pinterest users, you'll soon be pinning in your sleep*.
Launched in May 2011 with 418,000 members, Pinterest (if you've escaped the hyperbole) is the social networking site which hit 11.7 million unique US monthly visitors this January.
Pinning pictures of your favourite thing on Pinterest is so addictive, the site smashed the 10 million users mark faster than any other independent American site, according to Comscore.
ComScore also said that on average, Pinterest users spend 98 minutes on the site each month. Utter nonsense that. We know Pinterest users who are obsessed with the medium and spend at least 98 minutes on the site every day - squeezing in a pin at lunch, between meetings and last thing at night.
Pinterest is one of the best possible ways to waste time online, so if you've heard of it and want to get involved, we've put together a list of top tips to make you a class A pinner.
