Hmm...nice idea but nah thanks.
If you'd pay attention to half the conversations that go on here, you'd see
that the topic changes constantly and it's usually game for more than one
person. So more than one topic. It would be even more confusing
changing the subject all the time than it would be to just reply to what was
said.
Portion of the post dulls that confusion. One subject keeps it in
some kind of order for smaller posts. When a larger discussion takes
place, then the subject changes.
So thanks for the suggestion! But I doubt it'll change.
