It's more a convenience factor than anything. I periodically nuke all my temp files and cookies on my laptop and scan for malicious crap. That would be one more site I'd have to remember to go back in to save user/pass and set preferences for after each pass. Not worth it when all I do is look crap up on the site and never post anything.
The point is they changed the base layout, making the site worse and they should set it back.
