How would you propose to enforce limitations on two-person conversations in threads? To me, all it would do is prevent the exchange of valuable information, to satisfy the sensibilities of a few. It's no different from the if-you-don't-like-it,-don't-read-it dilemma. If you're bored with the conversation, it's more productive to write a new post in the thread that links back to the original topic, than to try to prevent the current conversation through arbitrary limitations.
I still don't understand what prevents others from joining the dialog if they want. No one has claimed the dialog is not meant for everyone to read. If there's a thread that only two people are interested in enough to contribute to, that may make it an unpopular thread, but that doesn't make it rude.
One word: relevance. I don't see anything wrong with a "conversation" of sorts between two people going on in a thread as long as the posts contribute to the topic at hand. Anybody else can jump in and add to it that way. What's disruptive is when somebody picks up on a detail in one person's post and gets in a conversation about it that has nothing to do with the original post in the topic. Just as an example, I remember Civet posting a topic a while back asking for people's opinions on where on the autistic spectrum she was. Someone (I don't remember who) saw she mentioned taking an online personality test and asked Civet to post a link, which she did. From that point on, the topic shifted focus to everybody posting their own results from the test.
I think that's the sort of thing that can really be hard to sift through. In its own topic, the personality test would have been interesting, but these radical shifts of topic tend to make posting and reading a little less enjoyable for everyone, especially topic starters.
