Marc Andreessen's blog is pure goodness. His post on hiring / firing and HR for startups just rules. As do almost all of his posts. In 1 month, he's already written enough good stuff to make a best-selling book.
I don't understand why his domain name is "pmarca.com" What's the p for?
I recently saw him walking around in Palo Alto. He's bald as a ping-pong ball, but still looks pretty young. I think he still likes to eat at The Creamery.
