It could be interesting- the challenge would be to incentivize quality and participation. And at least IMO it's much more interesting to see different perspectives argued on a topic, rather than actual rebuttal in most cases, or even "yes, and" confirmation. Certainly I don't enjoy the sort of quoting line by line and picking each apart that sometimes seems to happen on forums.

In order to incentivize good essays, something that was paid like substack, with different perspectives lined up on different topics could be interesting. Maybe with authors aware of their opponent's central arguments so they could address the same thing instead of talk past each other.
