I was asked to be a Helpout person.
It was about two years ago. Had an interview, setup my Helpouts page etc. Was quite intrigued about the possibility. But then it suddenly went all 'happy clappy' as a lot of these type of web things do and as a Brit I just edged away from it. Some people just got a bit too over excited by it all.
Then a few months ago Google told all us Brit Helpouts folks we could no longer charge for our time...which was nice.
