Is the new bottle identical to the bottle after the sip was taken? That would mean each copy has less juice than the one before it. So although the total amount of juice increases when a copy is made (at least until the sip is larger than the remaining juice), it would still run out eventually.
The term I've heard is Threadiverse (i.e. Fediverse with threaded discussions), but that was coined before Threads launched so it's a little awkward now.
I don't know, but I have the same experience. I mainly use the subscriptions page, and rarely click on videos from channels I don't know. I think you need to find channel recommendations elsewhere and subscribe to them (or note the name at least).
This is a neat tool! I searched for "how are you?" and got almost the same graph so I'm not sure if it's as meaningful as people think. Probably more related to casual conversations being captured in text more.
It would have less every time someone drinks from it.
