While my job is always around dealing with scale issues, I have never encountered that with my personal projects, until today.
My website went down and that makes me happy. Ironic, but true. First, I thought I had messed something up (highly likely). But it turns out that the traffic took it down and my cheap servers didn't like the load they were seeing. First scaling problem. Yeah!
It is a great feeling to build something that people find useful. But it is only a beginning. The challenge is to continue building things that people love. And, shipping and iterating. Now, my mind is flooded with ideas on how to optimize the HBR project to handle more concurrency and load and I can spend time on it because it is real now.
