This sort of summaries always leave me with an impression of being written by someone about himself and a few guys in his epsilon neighborhood.<p>Realistically speaking, you've gotta be not just an über-programmer, but having extensive exposure to the HR and developer management to have any credibility on the matter. Otherwise the statistical sample is just not there, so the list has very little value outside of being entertaining.<p>A concrete gripe with this particular matrix - maintaining a blog has <i>nothing</i> to do with programmer's <i>competency</i>. In fact the exact opposite is true based on my observations. The reference to the value of TopCoder rankings is also laughable at best; again based on my own experience.
