So, after participating in the thread on new forums, and then seeing a separate conversation starter injected into the thread that was tangentially related, I did think of a Discourse feature that I wondered about the feasibility of - reply as a new topic. I envision having some kind of form at the bottom of the quick reply box that allowed for you to tick something (make a new thread from reply) and a space for the new topic's subject that would default to something that let you know that this was a reply to that topic ("re: topic name" as a suggestion). And perhaps a picker for the area, but by default, I think that the location of the original topic would be fine.
Thoughts?
