What is the rest of the money going to be used for?
Ad revenue will be used to help the community. Hosting the Bitcoin Wiki is an example of this. I also want to promote development of Bitcoin Core and other core Bitcoin technology.
Donations were meant to be used for running this site, creating software, etc. In order to use donations for other things, donators would need to agree to it. I might pursue this later. There's plenty of ad revenue to use first.
