Stage 2. Then men became Internet users and were allowed to give feedback on a 5-star basis. Internet users still have opinions and share them in form of “Comments”.
Stage 3. Following, users had the possibility to give a thumb up OR a thumb down. Users can reply to comments or even re-post them in their own opinion-stream.
Stage 4. More recently, users can “Like” stuff. No complexity whatsoever is necessary nor allowed. Similarly, any negative feedback is unpractical (or curtailed) since it would be bad form with respect to “business partners” of the site in use. Yes, it is possible to write something if you really, really care (which happens when you are upset about a service you paid for). However, other than in such case, who bothers about typing if they can just click.
But wait, there is more. The evolution of feedback and rating systems is not limited to the progressive simplification of the tools and the user interface. It rather (and more importantly) concerns what data are collected and associated with the users’ ratings.
The person who is rating content or items (the “rater”) has become the center of the action. This is somehow counterintuitive, yet the most valuable information for the website has nothing to do with the items rated thereby. In fact, the most valuable information is that one concerning the “rater”: its tastes, preferences, behavior, etc.
Therefore, it is key that such information is made as standard and accessible as possible. For this reason rating on one dimension (“Like” button) may work better and eliminates certain “noise” in users’ behavior analysis. Hence, simplification is functional to enhance user-profiling and, eventually, to better target those users with relevant ads.
I believe we can start looking at feedback and ratings from a different perspective. In fact, I have the impression that their social significance has changed as they do not represent anymore a vehicle to convey opinions but rather a form of basic interaction to show an acknowledgment that something does exist. To the contrary, if there is no “Like” button underneath it, such thing cannot be part of the user’s profile for advertising purposes. And, that somehow makes that piece of content invisible on the Internet.
