vidly logoVideo startup Vidly is holding true to its promise to expand beyond Twitter with a new tool called Vidly Express, an easy way to add video comments to any blog.

The San Francisco company says publishers just add some code to their site, and the code creates a button for video replies next to every post. Vidly Express also integrates with commenting system Disqus (used by VentureBeat, among many others).

vidly expressYou can see the feature live on the site of Vidly Express’ launch partner, hip hop artist (and tech conference regular) Chamillionaire. It slides in naturally next to the buttons for commenting, Facebook sharing, and retweeting on Twitter. Click on the button and the site asks you to leave a video reply. The design makes it easy to leave a message but relatively difficult to view the other comments — you have to click on a link to a separate page on the Vidly site. I wonder if this approach will encounter the same problems that Facebook/Twitter aggregator Seesmic encountered with its earlier technology, which focused on video chat, or if it will overcome those problems.

Vidly was originally called TwitVid.io. It has raised $500,000 from angel investors including Ron Conway.
