To be clear. I am not looking to discuss UX issues. Please do not put words in my mouth.
I want to ask questions like, "What are the strengths and weaknesses of [product]?" This is not a discussion to me. There are answers in there. Real Answers. Some of those answers will give me new wisdom that will help me be better at my craft. I want to vote on answers and see the reputation of people who answer with insight, thoughtfulness and design strength.
After spending a few minutes on chat, I would describe it as chaotic (at best). At worst, it is a 20 year old AOL bulletin board. There is absolutely nothing there that compares to the main interface.
This has long since entered the realm of depressing. Chat just doesn't work for this at all, in my humble opinion.
Here is a decent thought experiment:
- Go to the most popular questions (top 20 views) from top to bottom.
- How many answers are there on average?
- How many comments are there on average?
Ask yourself: Would a normal human being look at that page and say it's a "discussion"? I just asked a few people and they all said the questions and answers are fairly intense discussion/debates/conversation and true "answers" really don't apply for any of them.
The truth is UX.stackexchange doesn't have a single questions that can be conclusively answered in the StackOverflow sense. Every question can be debated. In code, either it works or it doesn't. In UX, things aren't so straight-forward.
There is a great article on this subject.

This is not a great answer to your question. I should give it -1. However, I didn't appreciate using my name to put words in my mouth.
