While there have been many attempts, no one has really seemed to get this whole social video thing down to a science quite yet. There has been no lack of interactive video technologies, although most tend to try to make certain elements clickable, like an image map, without actually encouraging any two-way dialogue.
Enter Viddler. Aside from being a great way to host your video (among dozens of others), Viddler also enables viewers to insert contextual comments that appear during specific times in the video in an almost Pop-Up Video kind of way. The result is an almost conversational stream of comments that appear in a context that seems much more natural than in a chronological listed format below the post.
Of course, this won’t address the main problems with consumer generated commenting, which are spamming, lack of civility and flame wars. Publishers will still need to find that careful balance between moderating and filtering or else everyone will be rushing to the first couple frames of the video to post their “this is teh suck!“
