How can we encourage more posts with comments here?

On this page, I see posts, but no comments. It's a see of death. The same is true of all game design subreddits. Despite this being a thing a lot of people find interesting, there doesn't seem to be any really successful community oriented way to talk about this type of thing.

What types of posts do you think we could make to bring this space to life?

Personally, I think in-depth reviews of games you've played a lot are the way to go. Say you're a grandmaster at chess. Give it a review. Have you played Monopoly into the ground? Critique it. I'd like to start discussing here to, what other ways are there to liven this up?

I also may start posting speculative designs. So, game rulesets I've come up with, asking for comments from others on what they think I should look out for.
