And many such sites are not protected, see `Hall of Shame` (link below)

Absolutely.

This is correct, given the current security indicators in browsers; I 
even have some empirical data to support this (but it is also common 
sense). However, the use of SSL may help _some_ users:
-- The few users who carefully check the URL, padlock, certificate
-- Users who install browsers/extensions providing improved 
security/identification indicators such as our TrustBar

People in favor of unprotected login pages (mostly people in charge of 
them?) claim that both users groups above are negligible and do not 
justify using SSL.

I disagree; for example, TrustBar is available thru multiple sites, and 
I have statistics only from http://addons.mozilla.org, and there I have 
over 25000 downloads. BTW this site also allows user feedback, which you 
are encouraged to leave, I read it carefully and I believe our next 
release will in fact take care of almost all concerns raised by users.

And of course there are other improved security indicators solutions 
such as Netcraft, TrustToolBar (although I don't like their privacy 
invasion and overhead).

This situation is also not helping convince browser folks to add the 
improved security UI to the browser (so I can get rid of developing 
TrustBar... have some other research projects to take care of!)
