I have used (stalked?) the StackExchange family of websites, and until recently, couldn't find a need to register: I usually found a similar question to mine, with an answer much better than I could think of. MUCH better.

Asking and answering questions is more art than science (is it?) but I don't know how to start becoming part of this online society.
Two questions I found particularly interesting:
- I don't want to kill any more mice, but my advisor insists that I must in order to get my PhD
- How to ask dumb questions?
