I just want to say that I am very appreciative of the quality content found on khanacademy.org. You folks are basically teaching quality online courses without tuition fees. You are helping people around the world who do not have the resources to attend school. Education is the best path for progress in suffering societies.
Heh, I wish I had that kinda cash to donate on a whim! The actually amount sent in that transaction is highlighted in red. :) About $100 USD in today's BTC/USD rates. The Total input/output is the amount sent/received by that address(1e4yhZqruTy5X7tJtPPLUcrfx9F67xyLL) since the beginning of time. That's not my address btw, that's one of BTC-e.com's internal operations addresses where I purchased and sent the BTC from. coinbase.com(without creditcard on file) will take 4 days to get BTC but I happened to have some USD in BTC-e.com that was handy for a quick BTC purchase. I don't actually hold BTC at the moment, only Litecoin. I only have coinbase.com to buy BTC, to send to BTC-e.com, to exchange for Litecoins.
Consider having a bitcoin donation address.
Thanks,
