My elder brother Anson has signed up BlueHost yesterday. He said from signed up, filling up of credit card details to building his first empty blog took only 5 minutes. It was amazing! I have read earlier that their activation process is fully automated and you don't even have to get email confirmation and activation code etc before you step ahead using one click installation to install your first blog on WordPress.
Anson is going to try creating additional domain/site, in due course I'll give it a try. Anson is currently waiting to get his domain ez-baking.com moved over to BlueHost and from my recent experience here in this post this process may take 24-36 hours before dns servers of major ISP's updated.
