I think it's safe to say by now that this site attracts a very broad spectrum of questions many of which belong on other SE sites. Unfortunately the migration system only allows us to migrate questions to ServerFault and StackOverflow.
Why don't we have a complete list of sites to choose from? Or at least a complete list of related sites?
If this were possible, I'd day SuperUser, Programming, WordPress, and Webapps should be added to the list as they are the ones we would use the most often.
