Maddbaron, it is good to see another brother that is hungry for the world that our parents, our grandparents and even most of us in the present have never had a chance to lust after and really HAVE it. Now that I have put my soap box up...
just to keep a good pulse on big business and what billionaires tend to look like, I totally recommend Forbes. You need emerging markets, check out this magazine I just found out about over Christmas, Business 2.0. Another magazine, that may round you out is Fast Company.
I DO NOT impress easily with magazine subscriptions nor do I subscribe heavily. I recommend reading them at the library and if the information is critical, buy a subscription. I am just now learning about RSS feeds and have not gotten into financial blogs even though I blog about other things.
I hope this helps. I got a little bread and butter that I keep under the lid. You sound serious so PM me if you are. I hope this helps. Not trying to shine, just trying to share.
