If I have a question concerning CentOS 6, I would use the common tag centos and maybe also the less commonly used tag centos6. Is it a good idea to add the tag redhat for these questions?
As CentOS claims to be binary compatible with RedHat Enterprise Linux (RHEL) I assume questions about CentOS would also be interesting to RHEL users. But on the other hand if I add the tag redhat, the tagging of my question will be less precise.
