Ranking Information
The site looks at all comments written during the day and updates the rankings for artists and photographers. This is done nightly.

If an artist is fortunate enough to move up the ranking an arrow will appear in his or her signature and profile. Often the site will also show the number of places that the artist moved up the rank.

An Example:

This artist is currently ranked at 45 and has moved up two spots in the ranking.

Generally artists move up the ranking quickly when a well received artwork is posted. A hot work can turn the heat up (indicated by the popularity rating shown in an artists profile).
