Some interesting articles linked from the Y Combinator resources page:

• Valuation, i.e. how the VC's money is safer
  
• If you want an NDA, you are probably paranoid and perhaps delusional
• Larry and Sergey are the crazy and self-destructive core of Google
• Is that venture capital in your pocket or are you just happy to see me?

I've only started reading these but they're an interesting crop. And Y Combinator is an interesting group; I wonder how many applications they got for their summer founders program.
