I'm not sure when the clock will expire; however, I'm acutely aware of the existence of the aforementioned clock. Yesterday, Chatty users were treated to an unintentional preview of a constant Chatty stream.
Due to some scheduling confusion regarding the holiday, there was no one around to hit Evening Reading. What's interesting is that, as yesterday's Chatty ran for 24 hours, we were about to see how the weekday conversation flowed as a singular stream. The world didn't end and conversation moved well, so I don't think the world will end when we make the switch later this week.
Of course, the new Chatty is a little more evolved than that, but you'll see what we mean soon enough. [Insert harrowing orchestral score here.]
