How successful have donations been with your site?
wensing: Stormpulse.com received a few $k in donations in September '08 (during Gustav, Ike, and co).  We slapped up a "Donate Now" PayPal button in the top-right-hand corner and it worked.  The benefit of PayPal over others is the fact that PayPal is an actual payment, not just a pledge to pay (which can be the case with other donation widgets).Word to the wise: be smart about minimums and maximums.  If you ask for a dollar, you get a dollar.  Ask for $20, or make it completely open, and you might get more.  There's obviously a psychology to it worth studying.That said, donations are not our revenue model, so we've taken the button down. :-)
