I'd throw in a suggestion of: dancing.
You'd be surprised how many introverted people do social dancing. And the bar is usually very low. So, not being a long time dancer, musically gifted, etc, is seldom a problem.

The only downside (for some) is that scheduling can be inflexible, and it's usually an evening activity so not great for early birds.
