I know, I know, Ubuntu is easier for beginners and more popular, but why does Stack Exchange have an Ask Ubuntu site but not Ask CentOS? Although CentOS is not so popular, it's still the top choice (for some things the No.1) for using as a web server, and also because of its unpopularity there are many questions that can't be solved.
As both are Linux and one is best for normal usage and one is best for server usage, why do we have Ask Ubuntu but not Ask CentOS? Should we only ask questions at UNIX & Linux?
