Microblog
This module enables microblogging on Drupal sites using it.
Users can publish microblog updates, follow and be followed by other users, and reply to other users' microblog updates.
Module also provides "public timeline" page as well as followers and following pages, and a block of "recent microblog updates."
It does not (currently) provide an API for accepting microblog updates from third party clients, nor does it attempt to push status updates to third party sites - the focus is on microblogging within the community of users on the site.
