def self.info
<<-INFO
The User Klout Topics module can be used to retrieve the general topics that
users in the currently active workspace are tweeting about.

#{'Note:'.bold} This module requires that users have been enriched with their
Klout ID from the #{'users/klout_id'.bold} module. It also requires that Birdwatcher has
been configured with one or more Klout API keys in order to work.
