Three things I like about stackoverflow (and stackexchange in general): the license currently used (cc by-sa 3.0 with attribution required), the possibility to download the databases of all stackexchange websites and the abscence of registrationwall.

Interesting documents related to the C language:

• Understanding Integer Overflow in C/C++

Interesting documents related to software licensing:
