Researching and answering questions is a good way to learn a topic - exercises. I've also been driven away, but there seem pockets of goodness, e.g. bash people are super insightful and helpful. Perhaps a kind of society of affliction. I can see why, prima facie, linking your own site looks like spam. Seems there could be a way to facilitate this (e.g. authorise/whitelist legit sites; or even host them on SO), but probably out of scope - like "closed as "interesting". And links lose eyeballs, undermining SO's business model... hmmm... revenue-distortion sunk expertsexchange... perhaps soon time for another change?
