In line with yesterday’s discovery of the Viddler WP plugin, Riffly Webcam Video Comments also supports video or audio comments within WordPress:
Riffly is a free service that easily plugs into your site allowing visitors to create video and audio comments.
The service is advertising supported. We cover all the costs for bandwidth, servers, and maintenance. Optionally, we also offer Premium Riffly accounts that provide you with additional benefits, such as advertising removal, control panel access, analytics, and much more.
