Hey...I know SE has gone through some awesome changes. I love the site and have used it for a long time. It's changed the way I eat, cook, and think about food.
But the talk section kind of frustrates me. It's not a forum...and it's not just a comment section because you want users starting content rather than just reacting to content.
Unfortunately, there's no real way to respond and interact naturally with other SE'ers. To respond within a thread to another reply, all you can do is use the '@' symbol and hope that person manages to find their name in your post.
That inhibits so many potential interactions. It's a hassle to go and do that. If a talk thread gets past 20 comments, it becomes fairly bulky to deal with.
I don't know how to keep the structure of the section while adding better ways to interact. But some kind of notification system of...say...your name in someone else's post might be a starting point. At least then it won't require someone to constantly check every thread they comment in to see if anyone has replied to their post.
Again...just my 2 sense...not trying to step on toes!
