Mention of the database, no matter the popularity, are signals of its use and the activity of it's community. I guess it depends if you consider the definition of popularity as whether it's liked, or whether it's deployed and being used. They should make the raw data available if they want this to be believed. I'd like to know to which metrics most contribute to a specifics db's rank. I have a problem, however, with the use of google as a source. Not sure how you can trust it to give you an unbiased result now that it produces personalized results using who knows what (ie incognito on chrome still exposes IP addresses)
