Great job!<p>I can sort of relate. I worked on an infrastructure system, almost entirely alone, for ten years, before it was finally taken over by a capable team, and I was able to step away, and it took on a life of its own. It is now a worldwide standard, used daily, by thousands.<p>I say “sort of,” because it was never something I planned to make money on. It filled a need. Also, and it’s a long story, I had to weather a fairly hefty level of abuse during that time. The demographics of the target user base were … <i>challenging</i>.<p>It’s all good, now.<p>One thing all that time brought me, was a <i>really</i> high-Quality product. Lots of time to squash bugs, and iterate the UX.
