What is this? A blogposting using only jQuery's show() and hide()? And it's in the top of Hacker News? Do I need to say wtf?

I find sites that hide the login form to be extremely annoying, including Twitter. Keep the login form visible at all times and don't require an extra click for your users.

LinkedIn also hides its login form on another page - it assumes you want to sign up if you land on your profile page (e.g. from a bookmark) but you're logged out.

Is this frill worth making login completely inaccessible for anyone that doesn't blindly trust all scripts? Because the demo consists of a button that doesn't work, and no username nor password fields. Fortunately Twitter themselves don't have this problem.
