I often saw the questions with tags arranged in order by the no. of posts per tag. ie, the tags with higher number of questions will be placed first.
Tag ios having more questions than iphone and objective-c.
But in this question, iOS tag is placed after the other two tags.
While sorting the questions below the newest tab, the tags are placed by the order by which I stated above. But, If I switch to the votes tab, the tags are placed differently.
EDIT:
As it is mentioned here, the tags are placed based on their popularity, why is it not updated to the current popularity of the tag?
