After PhD: Academia or Industry?

Being a PhD student, I quite often have thoughts about "what will I be doing after I finish my PhD?".
Well, the obvious answer for me is, I want work in California at a cool company like Google, and I'm doing my best to make that happen, but being that not so easy, I sometimes also think about other options (not meaning that the way to academia is easier).

I heard of this guy and read his article sometimes (even posted something about his post: Logging is your friend), but I noticed his blog kinda first time - seems like an amazing guy: Matt Welsh.

He's been a professor at Harvard, and he has decided to move to Google quitting his professor job.

And he has written some nice posts about how it's like being a kind-of one-of-the-highest-profile (man, professor at Harvard!) academia, and how it's like working as a software engineer at Google, and how he likes better at Google: (1)'Why I'm leaving Harvard' and (2)Day in a life of a Googler.

And one of his colleague professor has posted that how he likes his job as a professor: Why I'm staying at Harvard.

And just going through his blogposts, there are a lot more interesting stories about PhDs (1)Getting started as a PhD student (2)So, you want to go to grad school, and Facebook founder! (1)In defence of Mark Zuckerberg (2)How I almost killed Facebook.

being an academic, or being in the industry

or will he be happy being an entrepreneur?
