While millions of people come to Stack Overflow to find answers to their programming questions, there are well over a hundred sites within the Stack Exchange network, covering all kinds of topics from linguistics to bitcoin to Christianity. We found that our question and answer format, along with a strong community focus, could be readily applied to a wide range of topics. As proof, many of those sites have lasted a decade or more, which, on the internet, is a lifetime.

Today, we want to celebrate those communities that have endured for ten years, maintaining strong, active communities and building up a wealth of knowledge in their domains. The six sites that have anniversaries this quarter cover a lot of diverse ground, but still find new questions to ask. These sites are listed below, along with some links to interesting or popular questions and the top tag on each site.


A site for questions and answers about cryptography. Most questions are about modern cryptography, and the site design reflects this. The site supports MathJax / TeX, as cryptography is based on mathematics. Many capable users can answer even the most technical questions. The site welcomes questions about topics such as post-quantum cryptography, cryptographic hash functions, and algorithms such as RSA and AES.
