Let's see....
I started by being a partner in the now defunct Ultracash

Damn, Ultracash was good back then.
I then was the Vice President of Marketing for Cybererotica
And until last month, I was the Director of Marketing for Flashcash.
I also ran several free sites here and there but the 3 I mentioned were the big ones.
I was also a founding member of YNOT back when YNOT was an exclusive club and I wrote the code of ethics for them that it seems, everyone honest seems to still follow today.
