I don’t think it is a platform issue, but more of an online culture issue. In the age of Twitter, Snapchat, and yes, even the short lived ‘Yo!’ app, messaging has transformed into a piecemeal, situational event, with the expectation that the other party is ‘always on’ and waiting.
Older forms of communication (yes, I include emails in this) had the expectation that there was a middle man ‘storehouse’ where the messages would go to be held until collected by the receiving party, hence the requirement for the original message to contain all relevant information, ready for immediate consumption. The elimination of even the perception of a middle man has imbued a false sense of urgency on almost every communication these days.
In many ways, we are falling back to how pieces of technology tend to communicate with each other via a simple SYN/ACK protocol with the original message broken down into smaller chunks.
Nomenclature is also important. The very definition of a ‘ping’ harks back to the days of naval ops, where a ping was just a monotonic, generic, omni-directional signal sent out for the specific purpose of seeing what was out there (or announcing one’s presence) https://www.youtube.com/watch?v=jr0JaXfKj68
Redefining the purpose of the communique at the outset might help to reframe the format of the message in the mind of the sender.
