What doe the popularity bar indicate?
I don't have an answer, just a comment:
I performed a Gxxxxxe search and found that a great number of want to be knowledgeable people had an even greater number of unusable speculations as to the actual purpose of the bar in question. Quite amazing.
Perhaps someone may actually know and share the information with us. Thanks in advance.
