Just seen the article about the history of the Smart Logic of Chat’s “…is typing” indicator. The intention was to avoid parallel typing by both chat partners.
I thought that it might be a nice concept to create a type of sequential communication channel. Only one person can write at the given moment the message (walkie talkie model) and it can be extended so only one message can be sent (for a long period of time) up until the receiving person does not answer. This way, the message becomes some kind of playing ball. That’s the rule – take it or leave it!
The channel strongly drives the equally spread conversation, more interactive and more dynamic.
