I've been wondering about this one often enough. When I look at the pictures of the day and week on the front page, I wonder what the heck makes people vote high and plenty on most of them. A picture of the day or week, in my opinion, should not only have an outstanding motive, but should also be outstanding in artistic aspects (composition, colors, post processing etc.). A random snapshot that happened to be taken of an object of general interest in good weather really isn't enough to make it stand out to me. I wouldn't even find some of them worth keeping had I taken them. Guess some people are just too easily impressed.
Then again I see great pictures that went completely unnoticed.
Just wondering... *rant*
