I think its not a bad idea, but i would like to build on it. The way I interpreted this is that after one year you can change your name as much as you want. I think there should be a kind of timer, and you can change your name after 365 days, then you don't have to change your name right at 365 days, but when you do, it resets the timer back to 365 days. However, I think you should still be able to buy a new name, but once again, after you buy your new name, the timer for a free change goes back to 365 days. This is just my thoughts though.
