There’s a new Wiki for entrepreneurs that you can find here.  Most sources for entrepreneurs are crap: get-rich schemes, dumb-ass advice from some guy with an envelope-stuffing business, etc.  This one is notable for the people who are involved in the early stages, most of whom seem to have some deeper, richer information to share.

For a definition of wikis go here, or read this:
