People sometimes ask me for advice about starting a company. Here are some documents I've written which may or may not be helpful to you.

• hiring
• venture
• ptime
• nda
• trust
• usability
• happy (ok not really related)
• cake (ok not really about a startup)

And here's an article that Inc Magazine recently (Feb 2010) was kind enough to solict with me. :)

Good luck with your idea!
