Here’s a nice treat from YouTube recently. They’ve given us an ad(albeit an ad for their own website features) that mimics their top navigation bar, and it’s placed perfectly in my viewport to where, if I scroll down to watch a video, it looks like the menu bar is still there.

Here’s how it looks compared to the actual menu. It’s an exact replica but smaller.

Once you scroll down, you can easily be fooled into thinking it’s the real menu. I clicked on the search bar several times, thinking it was the actual search bar.
This is ridiculous, and for a company recently bought by Google, I would expect better usability. Yes, I was listening to “This is Why I’m Hot” by MIMS. Problem?
