* If you call yourself a hacker you are very likely not a hacker. If you are convinced that you are a hacker without saying it there is also a strong probability that you're nothing more than a wannabe hacker.
* I couldn't stress more ethics. The term hacker has been watered down to a point where it's impossible to relate it to the mentality of the first hackers. Here is a very small world but the way I see self proclaimed hackers on HN is a bunch of people who want to build something to make money. They don't care about ethics, about privacy, about their users. It's totally contrary to the ethics of old-school hackers.
Anyway I am not a hacker and I'm happy not be one, and wanting to be one is pretty laughable, you're just called a hacker by your peers, the rest is a pride problem.
