I'm always not sure when a conversation will need a thread. Sometimes I start a thread and then it's over with just one message that provides the answer. Other times I don't start one right away, but now if I start one then the first 4 messages of context will be missing at the top. I would use threads ofif there were a way to create them retroactively.
