We don't need to be able to comment on EVERYTHING. Unless you actively plan to use the comments for something, I think most sites should just remove them.

It's fine to give people a outlet, a place for them to let their voice be heard. It often just misused and not a core feature for most sites. Even Youtube barely need comments.

What I believe we need is a revival of the forum sites. Give people place beyond Reddit and Facebook to debate. More 4chan and less Disqus.
