Some early numbers on the quickly growing world of online donations from three major systems providers:

• Convio reports a more than 40% increase in donation dollars for 2010. That follows a 34% rise in 2009.
• Blackbaud, after reporting meaningful increases every month (scroll-down right side-bar), reported a 10% increase during December.
• Network for Good says the number of donations processed was up 20% for 2010.

We’ll have more over the next few weeks.
