Sometimes people prefer donations instead of ads.
There was a good discussion going on HERE.
So one of the innovative ways is the WP Plugin, Buy Me A Beer.
Another nice one is on GayaDesign.com(look at the sidebar).
It says "Buy Me A Pizza".
Well, if I really like the content and it helps me I always do my bit and donate.
Do you think these innovative ways can get people to donate more?
