There needs to be a better way of handling group conversations. IRC uses the constant scroll mentality. Email has reply-at-top, reply-at-bottom, and reply-inline.
Forums, reddit, Google+, Facebook, Twitter, and the like have a scroll-like view – every new post is merely sequentially listed after the last.
This can all lead to highly confusing digital conversations.
Somebody should make a parallel (maybe columnar) discussion/chat/email system where every participant can get their own space to reply, they can reply to specific things from different people, and everything can be viewed in an identified manner. Similar to how Track Changes works in Microsoft Word.
Surely it should be That Difficult™ to do this, should it?
