Something you may have noticed during your latest visit to the VMware Knowledge Base is a new rating system (see red arrow in screencap).

Rating Knowledge Base Articles

The Knowledge base Team wants to know your opinion of its articles in the
knowledge base. Five stars is a good rating, and one star is poor.
VMware considers a 4 or 5 rating as indicating the article is a
success.  Anything 3 or below is considered an article that requires work/improvements.

There’s also a Provide Feedback link. This opens a
new window giving you the opportunity to provide us even more feedback
on the knowledge base article. See example:
