How good is Chambers at giving constructive feedback on writing?

I can't help but wonder how well a post on r/writing_critiques or r/rant would do. I've seen good feedback on r/rant, but am not particularly aware of how well r/writing_critiques works. Would be interesting to know how well other writing communities work too.<br><br>&#x200B;<br><br>\* Looks at that new post on r/relationships with 1000+ comments.<br><br>&#x200B;<br><br>&#x200B;
