Does favoritism play a role in this site?

I have a general question regarding this site, over the past few days I have been more frequent and have noticed that my answers rarely receive “great answer” even when they are far more informative than others. Now granted it is a subjective function I have witnessed this conistently, for the same users.

Is it possible that people play favorites here? Only read/support answers submitted by their familiar peers? Or is it really impartial and I am only imagining a pattern due to not receiving the amount of points I deem worthy?
