No way is Google going to simply be defined by content length.
Look up real estate marketing and the results are in descending order pretty much by length of page content.
Look up real estate for sale in any city and you get a page full of top results with no original content. Just inventory.
Google is obviously aware of more than one type of content and has a decent handle on when to serve it up.
This was a very short post but the point is already made.
