It's a sad day when Farmville can become a billion dollar business and Werner can't feed his kids. I'm curious if he's truly living on ~$20k/year. That seems ridiculously low for life in Germany. Or if he's got other sources of income to bolster that.

Either way, what really needs to happen is companies that build programs off his work need to make a concerted effort to donate to the project. Heck, set aside a small percentage of revenue and consider it a cost of business.
