How many of the tags you use to idendify yourself are actually group membership tags... e.g. pythonista, founder, etc.?

How many of the activities you do only make sense in the context of people (productive member of society stuff)? Even more, how many of the things you do are because of the consequences for or from others (feed your family, help your friends, do something recognized as really cool)?

Where "me" stops and society begins is always a bit fuzzy.
