There is one person that just kind of thinks out loud, or maybe pastes from things she's read on the internet. She just types and types nonstop, but she's not talking to anyone in particular. She doesn't really respond to anything people say back. She just talks to herself. I suppose she may have a mental problem so I try to just ignore her. One time the room went quiet in bible study room and she filled the whole room with talking to herself. It was a wall of rambling. It really makes it hard to follow any back and forth conversation in the room though. I have to mentally filter all her posts because it is never on topic.
If the content is interesting or relevant, it doesn't annoy me. I guess there is a point where things disrupt the conversations in the room and make pointless mental noise that disrupt any chat that is actually happening. I don't know how to precisely define where that point is, and imagine we all have a different toleration level for rambling interruptions.
