The TLC module produces a count of the incoming links from blogs indexed by Technorati and links to a search results page where users can see the individual posts linking to a node.
Features on Drupal5.x version:
Added more control over node types and taxonomy view. Fine-grained options.
Added more options in node body/teaser view. Now there are 4 choices: Disabled, Teaser View, Full-page View, Teaser and Full-page View. (Thanks to the service_link module and frjo for grained control).
