I really like the Donors Choose concept, and the way fundraising is becoming an open, crowdsourcing type process. It gives people the opportunity to find each other out in the metaverse and bring little bits together to move mountains.
One mountain in my network: the 12-yr old son of a friend of mine was recently diagnosed with type-1 diabetes. This is the first chronic disease their family has ever experienced, so they're trying to learn everything they can about it. They are participating in a Diabetes Walk to get involved and find out more about how to cope with this stuff, so they set up a donation page for their walk pledges and have already made their target! They would still like to be able to bring more to the foundation, though, so just in case anyone is interested, the link is here.
