Most of you already know I'm fond of transparency. Since the beginning in 2005, we're pretty open within the registered non-profit organization behind Slashgeo.org, and one of those symptoms of openness is our Open Budget which has just been updated. A link to it is permanently available at the bottom of the 'Top Donors' section in the right-hand side column. It's the first update for over 1.5 year... In order to respect Google's terms of service for AdSense, you won't find some details such as Flattr, AdSense and other similar revenues.
We're still about $3,000 in the red, but the last year has been much more balanced thanks to numerous donations, including a major one from Safe Software that propelled them at the top of our top donors list. Being financially in the red doesn't matter that much (that's still a relatively tiny amount) compared to the thousands of hours of geonews aggregation and site maintenance (it's all voluntary work). What is more important is you contributing, the way of your choosing, to Slashgeo. We're also always open to suggestions :-) Enjoy!
