One of my all-time favorite websites is paulgraham.com, which is published by LISP programmer, venture capitalist, and essayist Paul Graham (not the photographer). Paul and a partner were the founders and developers of ViaWeb.com, one of the first ASPs (application service providers) that allowed users to build their own online stores. Eventually ViaWeb.com was acquired by Yahoo! and their platform became the foundation to Yahoo! Stores.
Since then, Paul has published many intriguing essays on entrepreneurial topics (which are on his website) and started an early seed venture capitalist company call Y Combinator, which has funded such start-ups as reddit, justin.tv, and loopt.
Here is a speech by Paul at Start-up School '08, " How to Create a Successful Start-up"
