How can we best help? asks Craig of craigslist

I love Craig Newmark for a few reasons, including the mere existence of craigslist, his ongoing work as a customer service rep to really keep his ear to the ground, and of course, his awesome and generous work in Palestine! But his latest entry on the Huff Post endeared him to me even further. In A Personal Call to Service, Craig writes:

Like most humans, I'd like to save the world, but I figure I need a nap. So, I figured it'd be much easier to talk you into doing it, by talking up the efforts of people who are really effective at helping others...

I do see that Americans have always wanted to give others a break, that is, to serve.

I especially appreciated his comment that:

I take all this seriously, figuring that if someone is going to help out our general community, our nation, our world, I should help in the ways I can do best.

Working for an extremely rapidly starting-up start up, I know that I always try to keep perspective on how to best allocate my time and abilities so that I help the most. And it's not easy! So Craig's reflection on this point, and his respect the requests people have made of him are really inspiring! I explained a bit more in a comment on his post:

I agree about the American inclination to serve. Having worked in non-profits, and managed American volunteers, what I most appreciate about this aspect of our national identity is the self-interest. That might sound counter-intuitive, but an important part of what keeps me going, other than warm fuzzies, is everything I learn from the 'service' I do. I learn about myself, other people and cultures, new languages, how to do things with nothing, new ways to do things, reasons not to do things I would have done, and so on...

How can you help best?
