Lean Startups

I think I mostly agree with this post on why Lean Startups suck.

Listening just to customers, and following their leads doesn't differentiate you. It goes make sense to consider their opinions, but allowing them to drive too much of what you do isn't the answer.

I'm not sure if Lean Startups are the best way to do things, but watching what you do and being careful with your investments is always a good idea.

A higher P/E for more US jobs?

What do you think? I think it's a good post from Mark Cuban, and I try to run my business the way he does.
