<p>Early in Stack Exchange history, it was expected that graduated sites would be on their own domain, like <a href="http://stackoverflow.com">http://stackoverflow.com</a>. Since getting a catchy dotcom name at a reasonably cost is tricky, people came out with non obvious names such as <a href="http://crossvalidated.com">http://crossvalidated.com</a>. Then the plan changed, but the name stuck around and the dotcom address now redirects here. </p>

<p>The <a href="https://blog.stackoverflow.com/2010/10/domain-names-the-wrong-question/">blog post by Robert Cartaino</a> explains the reasons for the change of plan. Newer sites are expected to have a name that describes the topic as clearly as possible. </p>
