Share your culture, not just your product
People want to interact with other people. It's why people are increasingly looking to buy local for food and why sites like Etsy have such a tribal following. We want to buy from other people, not just a company.
Pinterest allows brands to show who they are, not just what they offer. It's a chance to give people a look into their culture and meet the people who make it all happen.
The "Today Show" has a board dedicated to Anchor Antics. It's a chance for people to see the anchors as just that -- people. And, it's an opportunity to gain access to a part of that brand most people couldn't experience first-hand.
Obama's campaign has created boards dedicated to his family lifestyle and his interests -- not just politics. I'm surprised a company like Zappos hasn't taken advantage of Pinterest in this way yet. It has talked a lot about how culture is a big part of its secret sauce. This would be a great place for people to see it in action.
Annie's Homegrown has a board that's just about things that make people at the company laugh. It shows personality. It says they're human. And that's a good thing.
