The Commentry module allows admins to prominently display selected comments alongside node content.
Comentry was created to address the issue many newspapers, publishers, and bloggers face when dealing with comments, which is that valuable and insightful comments are typically lost in the noise of lower quality comments.
Good quality, pertinent comments can enhance your content by adding additional relevant information, showing opposing viewpoints, and provide additional coverage of a topic.
Highlighted comments are also a great way to reward your community. For example, even with a technical post, there are often comments that contain additional useful information. Highlighting these comments has the benefit of enhancing your content and rewarding high quality contributors.
