Rosenfeld's book is an interesting discussion point WRT the claim that when newspapers finish dying, so will investigative journalism. Yes, I know he works (worked?) for the Chronicle, but if enough people buy his book, he can keep doing his thing. Which is good. And yes, I bought his book and you should too.
It's nice that several of the books are free (gratis) to download, but it's too bad that all the purchase links are to Amazon.
