In youtube, it's common for people to reply or comment to a video by recording a video reply of their own and posting it in youtube. The norm is reading an article and posting a text comment but now with more and more video comments, there exists a few pros and cons.

Cons of course that it takes longer to receive the comment. Viewing a video takes time to load while reading text is faster.

But with increasing broadband speeds, one day the future could possibly that all comments will be in video. You just scroll to a button or avatar image and the video starts playing. Possibly play a few videos at the same time.

Interaction will increase, you can see people's expressions. Imagine websites from being mostly text/articles to mostly videos. Instead of posting articles, you post videos that do most of the talking. Kinda like....TV channels?
