Q:

What does the up arrow in the "top posts" section of the user profile mean?

When I'm looking some user profiles via ios-app, I noticed that most of the time all visible user's "top posts" are marked with an up arrow sign. But sometimes, I see posts without this sign. Here they are (top posts from top users):

Link to the selected post

 

Link to the selected post

Link to the selected post

What does this arrow mean and why is it not showed on certain posts? 

A:

This will be fixed in 1.6.3.6.
The lack of arrow just meant that the title was really long and the system chose to collapse arrow before ellipsising the text.  Now the arrow won't collapse.
