Started www.24theory.com a year ago. First, just the solver, then the single-player game, then the challenger game, twitter/facebook daily game.
Now it’s one of the top 1 million sites on the internet according to Alexa. I know it’s a small step, but still. Quite happy about what has been achieved. Alexa top 100,000, here we come!
