Why steemit.com's Alexa Traffic Rank started stagnating?

According to both Alexa itself and Hive account@penguinpablo's daily stats, there is no significant inrease in the traffic "judge" of Steemit since early-to-mid September, while on the other hand, the number of daily active users is slightly increasing.

Did we reach a "local maximum" with our current traffic and exposure? Or is there any reason for it?

What do you think, will SMTs cause any change in it?
