What's the idea behind that "Submit a Story" uncollapsible floating tab on the left side of the page? Seems like you're obstructing a pretty important, content-dense part of the screen with something unimportant and obnoxious that doesn't even generate revenue. Please reconsider this design.

EDIT: It's come to my attention that this only appears to be an issue at 1024x768, which I'm currently using because I'm at work and my employer's computer hardware is ancient. This is probably not a problem for the typical user.
