Yeah, "member" is a weird name to appoint the "views". Furthermore, with "popularity" we never know if it includes a notion of good or not. For example, Sword Art Online is one of the most-seen anime but its score is not that high (7,22) so is it "popular" or just "known"?

Maybe the term "famous" is more appropriate to designate something known+good.

So :

• Sword Art Online is "popular" (high members and normal score)
• Fullmetal Alchemist: Brotherhood is "famous" (high members and high score)
• Gintama° is "good" and "unpopular" (few members but high score)

It is nearly like playing with words, but doing it in a foreign language is really hard :|

In the end, what is important is not the definition we have of these words (as data analysts) but the definition others have of these words (people who use the graph).

This comment makes no sense, sorry for the digression...
