Yes. There are better ways to manage this than merging threads, in my opinion. Though I don't envy the job of editing this site. Here would be an interesting experiment. Next time you are hosting a party, and you notice that there are, say, three groups of two or three people in their own circles, but all talking about the same thing, try forcing them all together into one big group of 8 people, and then say to them, "now talk."
