[No, I didn't burn the card...]
Alright, some more details here:
DonorsChoose is a charity that allows you to direct your contributions to a school or program of your choice in a grassroots manner. That way the money goes where you want it. If you want to help kids in inner-city NYC, you don't have to worry about your money going to Alabama or vice versa.
It's endorsed by Oprah. Steven Colbert is on the board of directors.
I don't have any kids, and I don't know of any programs that I'm particularly vested or interested in. So I could just pick a random sub-charity, but thought I'd give someone else the opportunity to direct the money to a cause that is important to them.
For 2 btc, worth about 14 bucks at this time, you can contribute $25 to a charity that you care about.
Take a look at the site and see if there are any programs of interest to you:
