MoodleBlog is in the news and apparently seen as a good addition to Moodle.

"There's some work also taking place in the integration of blog functionality within Moodle. Still a work-in-progress but this looks quite promising. I'm unsure whether this will offer blogs at site or course level only. It would be good if each student could have personal blog which they could choose to share with other users or not. There is a journal learning activity at the moment but that is more an assignment tool accessible by a single student and their teacher rather than a configurable private/shareable resource."
