Yahoo are idiots.
Yahoo used to be a simple to use reliable e-mail service. Now the site is cluttered with useless links and services -- it offered to notify my mobile of new mails, I applied and it assumed I was in the Ukraine.
I prefer to use the US portal for news, but Yahoo detects that I'm in the UK (this time) and impertinently over-rides my Home Page choice, sending me to the UK site full of nonsense about Z-list celebs in London.
Worse, the site is frequently marred by intrusive Flash ads -- meatballs raining on my e-mail text from some kids cartoon movie ad ? Keyboard freezes as the Flash hogs all resources. Only solution, crash out of my browser of choice and use Firefox with Flash blocking.
Hotmail is a refuge by comparison -- Microsoft didn't have to offer to buy Yahoo, the present management are simply destroying the business for them.
