Bad web design - 1

There are some websites with good design and some with very bad design. Sometimes one wonders how very basic things are not considered while designing websites, even by leading websites. One example I came across today was of LinkedIn main page. By and large, LinkedIn is a successful and user-friendly site. However it's main page LinkedIn.com has one major flaw. It has fields for new user creation, but only a link to open the login page for registered users. Now, every person who comes to LinkedIn will be new user only once. Every time after that the user will have to click twice before being able to login. Isn't this is a very basic thing that a website like LinkedIn should get correct? I wonder these guys miss it.
