Network for Good and Yahoo! are helping bloggers raise funds for nonprofits. Bloggers (or anyone with a website) can create a badge* for the nonprofit they want to support. Readers can click on the badge and make a gift to the cause. Yahoo and NFG will make a matching gift of up to $50K to the charity whose badge gets the most individual gifts (of any amount)
Thanks to the good folks at GlobalGiving for bringing this to my attention.
*A badge is one of those little icons you see, usually running up the right or left hand column of a website, that have a logo or a "click here" button)
