@Vylix: Hm, well, for stackoverflow, I started to hang around, as giving good answers gave me some sort of acceptance I was missing in real life at that time, and still some what am. Enjoying this sort of feedback was a reason for me, to even fully motivated learn C by its ISO/IEC:9899 standard '^.^ . To get more often this feeling.
For IPS its definitely also the encyclopedia usage part, but thats just a BIG HUGE chery on top of that for me. That post made me actually realize it. I'm not that different from what that user described. Despite not as incisive in all mentioned areas.
