Came across a very useful wiki called MediaOnTwitter. This wiki contains the a list of the reporters, journalists, and bloggers on Twitter. You can use this wiki in two ways:

  1. Finding people worth following.

  2. Getting in touch with reporters, journalists, and bloggers to pitch.

Two other useful sources of information about Twitter are:

  1. Twitter.alltop.com–aggregation of news about Twitter.

  2. Twitterati@alltop–compilation of the last five tweets of the Twitter elite.
