Leadership Styles

I had a few beers tonight with Derek Ellis of Tsuvo Social. We talked a lot about leadership styles and in some cases the lack there of. And as I sit here thinking about these styles that I have been exposed to in the past five years, I wonder who or what style I want to work for in my next endeavor.
I honestly can’t sit here and quote leadership styles. But it’s kind of like pornography at this point…I know it when I see it.
So yes, I could Google and read up on different styles and types, but I want to know from you…where have you been the most productive and the happiest…and how did you use that to further develop who you are as a working, contributing human being?
