I have been watching Mixergy for last two years as a non programmer and I can say it is worth watching. It has forced me to think what entrepreneurship is and motivated me to learn programming. If you criticize then do it constructively. I mean show me a site/blog which has brought so many founders (both successful and unsuccessful) to their knee to spit out their real life experience and I will take your word. And I am sure there are so many niches out there screaming to be exploited in other fields (biotech, pharma, commodities etc).
