A Debate on How to Finance an Investment Bank

I've written before about how challenging it is to write this blog - I can't really say anything controversial without the risk of offending a publisher or customer.  And then there's the problem where I want to write something and someone gets around to it faster and writes it much better than I could have.  After attending the Money:Tech dinner last night and sitting next to Roger Ehrenberg and listening to Nouriel Roubini I figured I'd post some highlights. But Roger beat me to it in a post titled Investment Banking 2.0: Into the Future and did a much better job than I would have.  Roger takes issue with Nouriel's (who he calls the axe of the apocalypse) view that the remaining investment banks must marry commercial banks. The O'Reilly team put on a terrific event last night; I'm sure the 2009 edition of Money:Tech will be just as good if not better than the 2008 debut.
