The point is that you have choice when the client is in control of finding a server where theres no dns entry for. When the server has it, there no competition, when you enter something into you firefox toolbar like lets say google (without the .com or .org). Without the wildcard dns, it will bring you to the google site. With it, you don't goto google at all and instead goto the isp's search page. This stuff should be on the client, so theres competition and the way things find domains that don't exist is better..
