How can I tell if I'm working with a savvy business person?
trapper: It is very hard. A few warning signs I have noticed over the years:- Superficial knowledge, but claim they know the field. When you dig deeper you find knowledge lacking. Wikipedia can help uncover this sometimes, amazingly.- Do not read new business books.- Haven't heard of "classic" books in the business world, 
e.g. good to great, crossing the chasm etc- Business model based on a poor understanding of technology (e.g. "User generated content but restricted access site")- No track record- 50 years old and not rich.- Afraid to execute (give them a hard task to complete which they could fail at and it won't get done).- I'm always right about stuff I know nothing about syndrome. You want a partner who is complementary; he should be able to recognise what you bring to the table and should defer to you when he doesn't know.Good luck!
