Thread:Forum:Use liquid threads in the forum?/On threads

The word "thread" in this context worries me. A thread is one-dimensional, a chain of replies to the immediately previous post. Here on RW, at least, discussions do not work that way: people go back, reply to earlier posts, expand, and the structure becomes branching and multidimensional. I'm not sure what bearing this has on anything, but I'm sure it's relevant somehow.
