I would like to know why http://serverfault.com/questions/361682/secure-sysadmin-friendly-registrar was closed as offtopic.

Reasons I see for not closing it are:

• One linked, similar, question was here on serverfault. Another was on web applications.
• If that question does not belong here, then where does it belong?
  Stack exchange now has loads of different sites that up to a few months ago did not exist, and topics partly overlap in questions like these.
  Are users meant to just guess where to post it? powerusers? webmasters? web applications since DNS hosting companies have "web applications" to manage DNS?
• Why close rather than move it?
