The only way I've found to get an idea of management is to consume (read, listen, watch) absolutely everything you can find about them and the company and let it all aggregate and cross-pollinate in your head until you form an impression. More an art than a science, IMO, though if you had to make a checklist, there are certain things that would get more value than others (large insider holding bought with personal money, actions consistent with long-term vision, etc).
