I think that the bitcoin faucet was a useful starting point for many people because they can test the bitcoin before understand it. Now, it our round to distribute more bitcoin to a wider people. Asking them to go the faucet themselves and give their email to an unknown website will demotivate most people. In my opinion, sending bitcoin to your friends directly in facebook is the most effective and convienent way for them to try. You are a much trustable source and you can give them guidances. If we can create environment for people to send bitcoin within friends just like playing game, then it is a success because they already know how to use it.
Because of the number of people joining the Bitcoin100, I would think that this campaign will be success as many people are willing to donate their bitcoin to charity. Here, you may also send the bitcoin to friends first and then ask them to send to the charity you want.
Anyone want to participate in it?
