title: Should admin be a subdomain or a namespace?
body: <p>When would you use a subdomain over a namespace? i.e. <a href="http://admin.foo.com" rel="nofollow">http://admin.foo.com</a> VS <a href="http://foo.com/admin" rel="nofollow">http://foo.com/admin</a></p>
  
  <p>Alternatively, I also like how api.foo.com looks VS foo.com/api. I also find, subdomains a bit tricky to set up.</p>
