That's exactly what this post is about. "Real-time" on the web often just means an app that allows multiple users to concurrently make updates to some piece of state, and for the changes to that state to be broadcast to all users so that all clients are kept consistent within a reasonable time frame, preferably as quickly as possible.
While the deadlines aren't as hard as in e.g. audio programming, "real-time multiplayer" apps can be said to be broken if there is a very large noticeable delay between a user editing something and the other users seeing that edit reflected in their local client.

Hard disagree. There is no deadline to meet time wise, only that a specific task must be completed in a specific order as quickly as possible. This implies managing state while keeping latency low which is a QoS problem.
