I believe "most commented" and "best rated" would be more meaningful to me than "most viewed".   This might eliminate some of the lurker factor..but still would not be an accurate reflection of what members prefer.   Some folks simply do not rate or comment.

I quit rating images a good while back, prefering to comment only.

I  wonder what the folks who visit this forum prefer in genre.  Seems a poll of posters would be about the only reasonable way to discover that..still, many would not respond for various reasons.  Some, like me, have preferences which seem to change with the images on galleries..open to most all photo genres and caught by the image more than the genre.
