Some startups will be worth it (eg: Google, Facebook), but if you average them all, the risk/reward ratio is not worth it in general. There are a lot of crap startup out there, and you only have so many years.
Also, if you are a VC or a co-founder, then the risk/rewards ratio totally changes, and it's most definitely worth it. But if you are like the rest of us, then it's a big NO.
starting prices are a form of 'anchor' - a piece of information which is known to affect subsequent decisions. As the authors note, anchoring has a powerful influence on our reasoning:
I won't be surprised that FB be under $5 when the common employees finally get's their turn to sell (after all the VCs and founders who get's to sell first).
Yup, same experience here. If someone well respected leaves, moral can be completely destroyed. That person doesn't even have to be an important person.
One of the most interesting type of personality is the useless guy who brighten the office up, once they leave, the whole office can fall apart, especially if the office is full of strong personalities.
Most frameworks it is not possible to do proper unit test. With Angular, you can actually do it. As the controller is totally separate from the view (html/dom).
Do remember that Google has hired away pretty much all the top engineers already. You won't be able to get good people for cheap prices anymore.
