It seems like every page has a header saying:
Is this your first time here? Take a look at our Video Tutorials for using the site.
Does that text ever change? I have more than 200 rep, so I'm not a new user. The tutorials aren't new.
I think it bothers me so much because there's so much space in the header. There's a big blank space next to "Ask question". Maybe we could use that blank space to showcase new features (like videos) instead of adding the perma-bar underneath.
