Since a 7/10 for you may not be a 7/10 for me, several music rating sites, such as rateyourmusic, let you put “subtitles” for each rating numeric on your profile. For example, 5 stars can be set as “The Best” and .5 star can be set as “The Worst”.
Many people also do this in their user bios on this site, but I refrain myself from doing it because it just looks messy and takes up precious space in your user bio.
I think this would be a great addition to the features on the site.
