How We Built r/Place
I love write-ups like this because they are such a nice contrast to the too-common comments on Reddit and HN where people claim that they could rebuild FB or Uber as a side project. Something as superficially trivial as the r&#x2F;Place requires a tremendous amount of effort to run smoothly and there are countless gotchas and issues that you&#x27;d never even begin to consider unless you really tried to implement it yourself. Big thanks to Reddit for the fun experiment and for sharing with us some of the engineering lessons behind it.
