(BTW, I'm doing a startup in Boston. I'm sure they'll get lots of applications, but this isn't for me.)
Edit: I saw someone recommend their book. Let me plug another one. I'm loving Steven Blank's Four Steps To the Epiphany (http://www.amazon.com/Four-Steps-Epiphany-Steven-Blank/dp/09...)

Hrm... can't find it. Am I remembering correctly?
On the other hand, I think the advice in this book is fantastic. Two examples of things discussed:
1) Deciding what type of market you are entering (existing, re-segmented, new) and the consequences of each market type.
2) Confirming your hypothesis before you try to scale.
Get past the micro errors. The content really is quite good. Or I think it's good. What the hell do I know. There's a scene in Moonstruck where one of the characters seeks advice until she gets the answer she wanted to hear in the first place ('maybe they're afraid of dying?'). There may be some of that going on with me and this book.
Like I said though, that was just a vague notion I had. I haven't read the book, but do enjoy reading the stuff he posts to his site a lot.
