Toby Kurien: "It seems a chore to add all my posts to a GemThread server, just in case anyone wants to respond. Otherwise, the person responding will have to add the original thread and the response thread. Not a train-smash, but this may be a barrier."
I agree with this. It seems like the primary use pattern will be that a person finds a thread that they want to respond to, they add the thread to a gemthread server, and then they add their response. It feels like there is an opportunity for some sort of automatic initiation protocol, or perhaps some sort of dovetail with geminimention.
