Well i think a forum is not the perfect place for real time information and thought exchange, it is more for general advice and to have a chat about general stuff that is valid for more than just a few minutes. For real time conversations and updates and stuff like that you need to join telegram or other messagers. Also even though i think that it would be possible and pretty easy for bitcointalk to implement a chatbox (they exist as premade modules) i don't think this would add much value to this forum in the end all those chatboxes are just full of people that are shilling their own coin even if it is a total sh*t-project. You just need to look at the chatboxes of exchanges to see that.
