For those of you who followed Beth Kanter's fundraising campaign for the Sharing Foundation using ChipIn, you saw how it can be a powerful tool for nonprofits. ChipIn will even be adding features in January specially designed for nonprofits (full disclosure, I am on their nonprofit advisory board).  They have been nominated for a Widget of the Year award on Mashable, but the competition is stiff, and they'll need lots of votes to win.

If you'd like to help ChipIn out, click here, scroll down to the bottom of the page, and in the comments box type: "vote: chipin."  Correction: Voting for the Social Networking Awards has ended.  Here are the winners.

The do-good collaborative blog, WorldChanging, also needs your help to win. Yahoo! is offering a $50,000 matching grant for the nonprofit that gets the largest number of donations before the end of the year using its new "Charity Badges" that Yahoo! for Good has created in partnership with Network for Good.  For this grant, what matters is not the number of dollars, but the number of donors. So, by donating 10 dollars to WorldChanging, you can potentially help them win fifty thousand dollars. 

If you'd like to help WorldChanging out, click on this link to their Network for Good charity badge and then click on the "donate" button.  You can also click on the badge on the WorldChanging home page.  WorldChanging is a 501(c)3 so you can get a tax deduction for your donation. (Full disclosure, I contribute to WorldChanging's San Francisco blog).

There are also lots of other awesome nonprofits competing for the grant who you can help win (like the Sharing Foundation). Check out some of the orgs in the running here.
