• Linking student posts with the assignments
• Linking comments with the participants
• Unrelated posts in the course feed
• Only recent items are available in the RSS/Atom feeds
Conclusions and future work
Evaluation
• User testing in Tallinn University: 4 courses running
• Think aloud usability testing
Future work
• Aggregating recent content from various Web 2.0 services
• Providing visualization widgets for external web sites
• Archiving the course posts and comments
Value for the open education
• Portal of open courses
• Learners can create their personal learning environments
• Can be used as a central component of the learning environment or just as an enrollment tool
