Sounds like extortion to me. Seriously guys? You are going to tell a charity "I'll donate but only if you take it in bitcoin"?
You make it sound worse than it is. They want money and we want to donate to charity AND make people aware of bitcoin. Its win-win for both parties. Also consider not everyone has a credit/debit card or lives near a bank so bitcoin might be their only option for online donations.
I'll pledge 1 BTC.
