I registered the domain http://daily.12b.se/ and a lot of directories refuses to let me register because the use of a sub domain. I mean, "www" is also a sub domain but obviously treated differently. Does anyone know the effect of using a sub domain regarding directories, page ranks etc?
Directores dont like subdomains because people sometimes create hundreds of subdomains and try to submit them all. They reject subdomains the same as they reject deep linking url's.
