This form will calculate similarity between two users based on how they have rated quotes in the database, or if the 'other user' field is left blank, it will calculate the similarity between one user and all others.

Comparisons with few points of comparison—that is, when there is a low number of overlapping votes—are less accurate and tend to be skewed to extreme values. The similarity shown on user profile pages ignores any comparisons with less than twenty overlapping votes.
