Featured Comment Widget is a WordPress widget that allows you to showcase any comment that has been published on your site. Here is how the widget looks in the Dashboard, and on a site using the default Twenty Ten theme:

Installing this plugin adds the Featured Comment Widget to your list of available widgets in the ‘Widgets’ submenu (which you can find under ‘Appearance’ in your WordPress dashboard). Every comment has a numeric ID, and putting that ID in the widget form results in the that comment, along with the name and Gravatar of its commenter, showing in the sidebar. The Gravatar and username is automatically a link to that comment in its respective post.
The plugin is used throughout most of the week on Baristanet.

How does one find the ID of a comment?

If you don’t show meta data on your comments, you can still find it in the Dashboard under ‘Comments:’
