I agree that the use of MD5 should be discouraged, but I think forcing
a zero score would be an overkill. I am considering changing the way
certificate is done now (it's either 0 or 100) to include factors such
as signatures, validation type (e.g. EV certificates should be given a
higher score), etc.

I'd like to think of the assessment service as a public service. It's
only fair for the results to be public too.

I am not sure what you mean exactly, but I think the term "domain
name" is suitable. There are only subtle differences between domain
names and host names anyway. In the case of SSL servers, since
multiple domain names can map to a single host name, I think it's more
accurate to use the former. The term will make even more sense once
server name indications enters widespread use.
Also, I list the host name near the end of the assessment page.
