i know a great way to get more donations to the faucet: allow donators to leave a short piece of text. since the bitcoin faucet is such a popular url, donators could leave a link to their website or company, acting as an advertisement. public pilanthopy to new bitcoin users as a way to promote your company/brand image...
Neat idea-- I've been thinking about how to let people/companies sponsor the Faucet.The next couple of things on my TODO list are getting the 0.3.21 bitcoin release process started and an API for ClearCoin, but I might tackle Faucet donations after those are done.
