This should have appeal to folks of a certain age (like young). I haven't browsed enough company pages to say this is uncommon, but it's got a flare that most people don't have so it probably is uncommon. It does a good job of establishing the page as a dialog between the company and readers. This can be a valuable tool, although it takes a web jockey who has the right kind of writing style and people touch. And it probably doesn't fit every kind of business. I'm trying to imagine a funeral home page "Well, your friend's dead and that sucks. But you can win $10,000 for referring people to our 'Drop Dead' contest and there's discounts on embalming fluid."
