I suppose they're becoming more-&-more like 'chat-conversations' (i.e. conversations in which all participants are RIGHT THERE and know what statement/reply you're questioning/answering). But that's not how they are, especially if you're alerted to new responses by-email! Take for instance this post (which I'm too unvetted to link-to ). The original post is a link to a grammar-question. The reply (as I read in my email, not even remembering what I asked) was "I wish I knew"---no mention of 'what it was they wish they knew,' so it's spoken as if I'm still there! Why do people think an original poster is so-'hovering over their posts' that they're immediately back in-context?
