I'm going to be perfectly honest with you: The fact that you list that you're a one-man operation, that you're 18 years old, and that you say you "achieved financial independence at the age of 16" is a big turn-off to me.
I know it shouldn't be. I don't want it to be. I'm sure you've built an awesome product/service. But I also know what I was like when I was 18, and I know how much I thought I knew and how I appeared to others.
But I can't lie -- this would prevent me from using the service at the moment. My domain names are very important -- and it raises too many questions. Did you master the security side of things? Have you considered all potential points of failure? Have you vetted this with folks with more experience in the industry? Etc.
I'm not trying to rain on the parade or put down this accomplishment. I think it is -awesome- that you've built and launched a product that looks (and probably is) this good. But I think you might want to reconsider how you present your background.
Which of course leads to a whole new set of questions -- should you just leave out your age entirely? I'm not sure. (Is it really relevant or is this just me being knee-jerk?)
Either way, best of luck and congrats on the launch.
