Better Usability With Object Direct Manipulation
Direct manipulation make users feel more comfortable using your website. Users have been using windows for a long time, so if you try to imitate this behavior users will probably understand your interface without problems.

One good design example is iGoogle, the customized Google homepage. Feeds looks like windows with titles, an “x” and a minus. All these give hints to users that those are actually windows and they will try to move it.
Google have also done this interface self explanatory and easy.
