but my "popularity" rank state unchanged, so i'm waiting +18 in rank... or not?
No, 18 new visitors does not mean that you get +18 in your rank. The number of points you get for the popularity factor is attributed basing on you rank amongst other competitors. That is a relative factor. Moreover, it depends not only on the number of visits, but also on the number of comments and votes. Please refer to the rules for more information.
