Kudos to Tim Buntel at Adobe for a series of blog posts about the buyer personas he needs to influence. After attending the Effective Product Marketing seminar, he developed a persona for a developer he named Chris and posted a description of the guy on his blog, Not Too Fluffy (love the Teddy Bear, Tim). The first of dozens of comments said that the post was "creepy" in its accuracy. More people chimed in with comments to confirm and build on Tim’s original thesis. Tim’s added a couple of new posts in the last few days to keep the conversation going and gain more input. This is a great example of leveraging the blogosphere to develop persona insights and engage buyers in a favorite pastime — talking about themselves.
