Volunteering is good. It's good for your career. It's good for your soul. (Assuming you believe you have one.) It's good for your character. (Assuming you believe you don't have a soul.) It can get you badges. (Well, one badge, anyway.) Generally it's also good for other people, too.
I've always done volunteer work. My people were church people, so there's a lot of volunteering there. (As opposed to the military, where their motto is "Never volunteer.") I've always been on committees and boards and execs, and run conferences and events, but I also muck in with emergency management and disasters. (I also train, so I know how to muck in when disaster strikes. This comes back to that "Generally it's also good for other people" part: you do have to prepare so you know how.)
Some of it's formal, some volunteering isn't. As well as being on committees and stuff, for years I did reviews of antivirus software and, later, technical literature. I did it for free, and created (over some years) a fair resource that many people found useful.
(I got paid, some, for the books that I wrote, so, technically, I guess it wasn't volunteering. However, as anyone who has written a technical book will tell you, it's an awful lot of work for very little pay, so it comes close. I figure my first book paid me about sixteen cents an hour ...)
These days I don't get paid for a lot of what I do, so I guess most of it is volunteering. I help out with the Vancouver Security SIG/ISC2 Chapter, and here on the "community." And other places ...
