You will notice that this list has eleven entries because Drupal core is the number one download in the list.

The ability to cross post from other publishing platforms is one of the hidden killer features in Drupal. I say that this feature is hidden because I rarely ever hear anyone discussing it in the Drupal forums. The feature is activated by a core module called Blog API.

Once activated, the Blog API module allows you to publish content from other sites to your blog on Drupal. The other site must support this type of cross posting in order for the process to work properly. The benefit in utilizing this feature is that you save time by not having to publish something twice.

This short video shows you how to install a contributed module.
