StackOverflow et al.? I enjoy helping people in fields where I have relevant experience (it think I do!), eg with computer issues, and SOs gamification of that (and other community knowledge) makes it into something of a leisure time activity for me on occasions. I take part in some FB groups (pottery related) in a similar way.
