It's not the same thing. On amazon you judge a book by its cover. On this site you judge it by its content

You are judging the book on the basis of a page here. Not much different from judging the book on basis of the cover.

The two are very different. A book is mostly prose, in black and white, by the author. A cover is graphic design elements (and even the text is treated as a design element on the cover), most often in color, created by someone else.
