What is the point of donation?  Wouldn't the dev mining outweigh donation?  Also, more people would use because they don't have to donate before seeing if it is worth it to them, especially people with only a few cards.  Currently, with donation and dev fee, I would never make up my money with only 3 cards, and small boost in hashrate.  I get 150MH stock, so its not worth donation $62 for a chance to make $10 more per month. I mostly have 470s, I like Claymore miner because there isn't voodoo donate, I promise its faster, and there are a lot of awesome features.
