The results are in

The informal survey of Twitter users (see post below) yielded some interesting stats:
— 9 in 10 of those responding said they had volunteered this year.
— 1 in 4 volunteer on a set schedule
— 3 in 4 volunteer as events or their heart moves them

Tweeples were most likely to split their time between:
— Mentoring and
— Sitting on boards and advising organizations
Half of the respondents chose those activities.
Next most-popular was political action — which makes sense, given that this is a presidential election year.
That was followed, in descending order, by:
— Fundraising
— Tutoring
— Faith promotion
— Other, which included: feeding the homeless through a church program, working in the arts, being a Compeer match, collecting items for battered women at the holidays, and working with at-risk kids at school (I'd likely have put that under mentoring or tutoring, but for the respondent it didn't seem to fit those categories so OK)

How often do the responding Tweeples volunteer? We are split:
1 in 3 volunteer monthly
1 in 3 volunteer randomly
1 in 5 volunteer weekly
and a very small set volunteer yearly (at the holidays) or never.

Why do Tweeples volunteer? Lots of motivations. Here's a sampling:
— "I believe in the causes."
— "I believe in humanity."
— "I makes me feel good, and I have skills to share."
— "To give back."
— "I am blessed with a little money and a little time — happy to help others."
— "Sense of civic responsibility inherited from my grandfather."
— "I think there could be a revolution, parents' overall inability scares me these days, the future is delicate."
— "To make a difference in the community."
— "Why not?"

Thanks to all who participated!
