The ability to post to Drupal Blogs from external clients using Blogapi is an valuable feature that was removed from Core in Drupal 6. There is a BlogAPI Contrib Module for Drupal 7 but it is not functional and has not had an updated release in over a year since the current maintainer has not had time to work on it.
