<p>Interesting.</p>
<p>I was perusing the “ratemyprofessor” site and noted that many professors get both extremely good and extremely poor ratings and comments from students. I decided that site is worthless because you don’t know anything about the people doing the rating.</p>
<p>Did someone downgrade a professor because they (the student) were lazy and thus flunked? Or had wrong expectations for the course? Or was the professor truly a lousy teacher? There is no way to know.</p>
<p>Edit: Conversely, did a glowing review come from someone who is related to the prof and wanted to help them out? Because to see both ends of the spectrum for the same professor makes you wonder.</p>
