Blogspot: Google Blogger Integration

This module allows users to update their Blogger (or Blogspot) account with their Drupal blog posts. Each time a user creates a new blog post on Drupal, or edits an existing one, the post will be pushed to their configured Blogger account(s).

Note: this is a one-way integration so it's only possible to update Blogger from your Drupal site, and not vice versa. If you want to do the reverse, then check out the Feeds module which allows you to import RSS or Atom feeds from basically anywhere.
