Marc before Marc
This week, someone compiled the entire pmarca (Mark Andressen) blog archive into a single PDF. Every post Marc Andreessen wrote between 2007 and 2009, when he was documenting startup patterns in real time on his personal blog.
The collection covers product/market fit, the onion theory of risk, when not to start a company, how big companies actually work, hiring for drive over credentials. Almost 200 pages of the thinking that became standard startup vocabulary.
If you're building something, it's useful to read the original context behind ideas that get repeated everywhere now. Save this one and search it often.
