It wouldn't surprise me to learn that the kind of people who used to go into physics now hack. After all, I have a phd in physics, and I find hacking to be really fun...

This comment is very, very interesting... I keep reading about physics people who now are running 2.0 companies and that kind of stuff. But my question for you is: don't you miss science when working on a 2.0 environment? Or how do you correlate one subject with the other?

Yes, I miss practicing science a lot. It was a blast to do (I did theoretical work, which included a lot of computer modeling). But really, being a scientist is a frame of mind. Being a practicing scientist is a different story.

I don't consider mine a 2.0, incidentally.

Thanks a lot for your interesting reply, I was very curious about it.
