"What's wrong with Hotmail?"

Plenty of things:

a) Here in the UK, the localised adverts are mainly for loans and mortgages. Then we wonder why house-prices are falling upwards and national average debt passing record levels. I consider all excessive advertising for "outgoing" financial services to be unethical.

b) Hotmail isn't XHTML-Compliant or Semantic Wink

c) Hotmail fails in Lynx

d) Hotmail flashes a "page cannot be reached" error when you try to log-in using Firefox before forwarding you to your account page

e) It's parent, MSN, is guilty of serving broken stylesheets to non-Microsoft browsers, most notable Opera.

f) Ironically, ever since Hotmail was taken over in 1997, it's always been slower. Originally it was written in compiled CGI. Hotmail is Microsoft/MSN's flagship internet application, yet doesn't use ASP.Net. That is surprising.

....And other things, I need not list them here.
