Be it YouTube, Facebook, Imgur or whatever site you can think of that has open commenting, there should be a daily top 10 comments listed somewhere on the page.  At it’s simplest it can be an automated product based on the likes or likes vs dislikes.  Now before you cry out that this is trivial and of no importance, please consider the possibility that commenting, in general, can be have a very positive effect on ones writing skills.   As we all know, grammar and spelling errors are corrected instantly by the technically accurate trolls who seem to lie in wait, but I would say without a doubt, regular commenters who actually take in the feedback of others, are improving both their brevity as well as the relevance of their writing.   A top 10 list of the days most favorably responded to comments from all the posts within any of the big sites would be at the least a valuable read.

On a technical note, privacy could be preserved.  YouTube, not an issue as it’s all open, but Facebook could prompt the user, “You have one of the top 10 comments in Facebook today.  Click “everyone” now, to share this comment, and the original post with the Facebook community.”  This could be done for the original post as well, if applicable.  If the person with the original picture or post is not interested in sharing, then the computer just goes down the list to the next top rated comment.  Again, it would be completely automated.  The website owner would be allowing the users to generate additional content for their benefit and enjoyment, and yet another thing to come back to.
