My last post recently featured #1 on Hacker News. This surprises me a little bit because when I first posted the link, there were little interest (~15 points) in it. I shake it off and went on with my day. Few days later, when I was browsing Hacker News, my blog post was featured right there on the home page through someone else’s submission. The post stays at #1 for ~ 12 hours before drift off to page 2.

It was a .NET framework shop that struggled to scale in both performance and cost at the time.
