The Sensical Moment: Asking for User Opinion When the Time is Right

This is something I've thought was important for a while. It didn't make sense to me that you could Digg something without even reading it. Of course, the same situation seems to exist here on HN. I'm not really sure if there is a good solution to that problem though.

The only thing I can think of is to get rid of upvoting - instead, auto upvote when a user clicks through. If the user doesn't like it, they can downvote the article (maybe some friction in having to find it again). Kind of a different spin and I'm not sure if it would work or not, but an interesting thought.
