StartSSL only allows validation for top level domains. So you can't get a cert for me.blogspot.com unless you own blogspot.com.

I think you entirely missed his point.

What about blogspot.co.uk? Do you need to own that, or co.uk to get a cert?

What counts as a "top level domain" is, as Animats said, complicated.

Oh ok. I can't attest to how this is handled because I have never attempted to get a cert for a domain like this.
