Thanks for the feedback. W3Counter has around 79,000 users despite never being advertised; I don't really care to grow it faster by giving away more. The PRO features cost money because they cost me more money -- they include real-time reports that take more server resources to scale.

W3Counter's always been a pet project I built for myself, back in the days before Google Analytics existed, that I've just been happy to see pay for itself. The site turned 10 this year.
