Ask HN: Thoughts about our video streaming debating app?

We are developing a video streaming debating platform in form of a website and we are wondering whether anyone likes it or not before going further with it.

The website let's you:

- Challenge a friend or a random stranger.

- Find spectators by advertising your debating room's link.

- Watch live and recorded debates.

- Vote for the side you are.

- Chat and comment on live/recorded debates.

What we care now:

1. Would you find this app useful or useless? why?

2. Would you initiate debate and/or spectate?

3. What else do you like this app to do?
