On May 1, 2009, JTA (self-described as “the Global News Service of the Jewish people”) published a list of the 100 Most Influential Jewish Twitterers.

Influence was measured by:

  • # followers & friends
  • ratio of friends: followers
  • most recent post
  • celebrities were eliminated
  • extreme twitterers whose # of tweets somewhat obscure dimensions of their Jewish identity

Almost all are from the US or Israel, and tweet a mixture of explicitly-Jewish and more secular tweets.  They also ranked the top 25 Most Influential Jewish Organizations and Newswires.  See the top 10 most influential, below:
