Well, I would suggest that "Unova Travel Journal" doesn't need to be a sticky either, but this type of thing is a matter of opinion. ;) I like the idea of stickying something that is limited-time, and the caption contest qualifies, later unstickied at the end and replaced with the new one. I recall you used to stick weekly polls as well.
As for screen size, this (linked for size) is how big my view is give or take a couple rows of pixels (I cropped the taskbar and bits above the URL bar, and my "Find" bit which was up when I took the picture, out of the shot). If I hit F11, it's even bigger. I know you cater to all screen sizes, however, and some are still smaller than mine. :)
I agree that the Quick Questions threads are needed, but why not merge FAQ and Fifth Gen guidelines? They both seem like separate "rules" threads. One should suffice, right? :)
DISCLAIMER: Not trying to tell what to do, obviously, just my thoughts on the stickies. Still your call.
