This is an idea that Reid Hoffman has advocated for a while now and that I fully support. It is also the reason why I think sites like Facebook and LinkedIn can never meet - your professional brand is something you want to control completely. I think that you should do product development on yourself and constantly reevaluate if you're headed in the right direction as a product that people want. It sounds odd to objectify yourself, but a lot of the same techniques related to iterative development can be readily applied to personal development.
