I have my .biz domain since 10 years now. Prices always increased a bit - fair enough. But 10%? How would you feel, if gas prices are going up 10%? You'd rant and call your politicians not that nice things, won't you? Or how would you feel, if your rent goes up 10% per year? If I get a raise by 2 to 3 percent per year - how do you justify 10%?! If you do it - I'll finally quit using .org / .biz / .info once and forever. Greed isn't nice.
