Ever since Wikipedia redesigned a year or so ago, I've had issues with their top navigation. Some people might think that it looks nicer or "opens up the page," but I can't say that I'm a fan.

Exhibit A:

As you can see, the top links (Article, Discussion, Read, Edit, etc.) don't have a clearly defined top boundary. This makes it impossible for the user to clearly perceive each link's dimensions.

A target's size is no better than its perceived size.

Chrome's original minimalism of having a default look lacking bookmark and menu toolbars has been mimicked by all of the major browser now. Not to be outdone, Chrome now looks to reduce the browser's non-content area even further by removing the address bar with its new compact view. If you have a recent Chromium or Chrome Dev release you can enable the new view of the about:flags screen.

What's next? Auto-hiding the remaining bit's of Chrome's chrome? I'm all for minimalism, but there might be a point where having some permanent interface elements might be useful. For one, it would appear as if the removal of the address bar would make phishing easier, since there is no way quickly check or monitor the domain of the sire you're currently visiting.

Sometimes a simple screen capture says it best:
