Why nav bar fixed?

I've just sent this to Confreaks :

"Hi, I'm longtime rails dev now and an heavily addicted to confreaks. I've been on your site for years wondering : when are they going to improve it. I even thought of volunteering at some point... But hey great you've finally done it. But please ! Please, please, please remove the nav-bar-fixed of your menu, it feels like I'm always bending to avoid banging my head on a roof conceived for dwarfs and it's hurting my back ! It's fine for mobile but desktop screens are large and proportionally have no height. The fixed nav bar is a pure heresy in such context and I'm sure we'll all get rid of soon like the <blink> tag and the flash intro soon. So why not do it now ? Thanks for your consideration"

Am I the only here ?
