#Kbin actually handles this really well. Whenever it detects 2 of the same #thread (at least that's how I think it works), it'll group them and only show one of the threads on your feed. If you click on it, right under the thread will be the other #cross-posted threads on other magazines, each of which has its own upvote/downvote and comment count. You can click on any of those threads to switch to a certain magazine's thread and see the #comments there. Also, when you comment, it only goes to the thread you currently have open.
