Buzz movers are the subjects with the greatest percentage increase in buzz index score from one day to the next.

Significant increases in buzz index score do not necessarily indicate huge overall interest in a subject. Greatest overall buzz is reflected by the list of buzz leaders.

For example, a subject that increases its buzz index score from 4.0 to 12.0 would have a one-day buzz move of 200%, which might qualify it for inclusion on the list of buzz movers. However, that same subject, with a buzz of 12.0, might not make that day's list of buzz leaders.
