In case it's not clear, I'm talking about the stupid, 105px tall black bar that asks you to "Join Coderwall" when you start to scroll
Unfortunately, having a massive black bar overhead gave me a feeling of claustrophobia. Made the reading intensely uncomfortable.
Generally speaking I find arguments about usability from someone who can't present their own blog a little dubious.
if you're trying to stifle those that would make contributions to this community then keep doing what you are doing.
Edit: I can type good
One of the seldom talked about problems with floating headers/footers is that they break page up/down. Hitting space bar now takes you slightly too far to keep reading uninterrupted.
If there are enough people like me that get tired of seeing this particular piece of visual spam it gets added to the list of elements that are blocked for all Adblock Plus users.
The lesson site designers and developers really need to start learning is STOP DOING THIS. Put a link in your nav, or at the top of the page.
Turning hover on for everything is annoying. Crap popping up on your page when I use the scrollbars is annoying. I really don't care how clever you think it is. It's just damned annoying.
