I used to be a major contributor on Superuser then one day the SO team had a competition to ship a reasonably decent spare graphics card to the most worthy requestor, based on a community vote.

I won in behalf of my young son, whose graphics card had just expired, but when the SO folks noticed I was in the UK, they decided shipping the card to me was too much effort and didn't send it.

That's when I decided my knowledge and free input would be better appreciated elsewhere and I quit. That was perhaps 12-ish years ago and I think I've been back a handful of times just out of curiosity.
