Pepsi is doing a monthly grant program with Web voting.
John's got a proposal there for OtherWorlds. I noticed a few days ago, but today he's posted about it. :>
And the 2010 Locus Poll is open. Nonsubscribers can indeed vote. Remember that you can write in candidates for 2009 works -- up to five per category.
Go check out the voting on both, eh?
