Maybe you heard about it, maybe not - but there are already some pretty cool ways to easilly add video posts and comments to your blog. First one is service called Seesmic. In fact I have it installed it already and it's a very, very cool way to interact. Check it out yourself (click the add a video comment below the comment box). Very cool thing about Seesmic is that you do not have to register to their service, you can just make the video (or voice if you dont have camera) comment and post it.
