I've had a bunch of domain names, sold a few and couldn't get rid of the others. Someone on afternic domain chat (when it was still open) asked me how much type-in they were getting. When I found out how to check it out, I realized that some of them were getting 100+/day which started growing once I placed sites on them and optimized. So basically, it started falling into place. I've been out of the game for a while, but getting back into it now
