nice article, but the concept of a career that is too much based on self-promotion and too little on actual production is not a concept invented by social media. It's fine to say, "hey don't waste all your time on twitter" but this seems to address people who specifically are pursuing their social media persona as a means to career advancement. It depends on the career.
