Amit Banerjee pinged me about a Google experiment he noticed over the weekend. He calls it a sticky top bar, where the top Google bar sticks to the top, even when you scroll.
Here is a static picture, also notice the new look for Google Instant Previews.
He even posted a screen cast of it in action:
Pretty interesting, don't you think?
So far, early feedback on this is positive. A "sticky" or "permanent" top bar is not a new concept, but would it be bad for Google to use?
