The best volunteering opportunities are those where one can learn something new and/or interact with those people which normally they wouldn't. I've washed dishes, worked in a warehouse, written code etc - they were all fun, but the dishwashing became boring after a few weeks. If every volunteering opportunity mentioned what people would learn, they might increase participation.
