In his blog Jason Calanis pointed to the CEO and co-founder of Wesabe, Jason Knight, who declared in the company web site, that all users can call him directly between 12 to 4 PM.
Loved it. This is exactly the approach a modern CEO should take. Complete transparency. Understanding that your customer is the center of the business is something we should all embrace.
From day one, when we launched our company web site, I put my direct mobile phone there. Yes, talking with customers can be time consuming, but it's also one of the best uses of my time.
As someone who need to direct this company, I want to be as close as possible to our customers. I want to hear what are the pain points for them. I want to learn what we could do better and what they expect from us in the future. I want to simply give them the opportunity to teach me about our business, because in the end of the day - they are our business!
