Words take on different meanings in different contexts, and get adopted in different domains all the time - this is how language works.

An example - "I'm going to ping Bob to see if he's available"

There are innumerable others.

Sure, this isn't "real-time" in the context of microcontrollers, and RTOS stuff, but in the web app context, I think it counts.

Right, but it would be best to stick with accurate technical definitions when discussing technical issues.

What I've learned from years of working with product managers is that anything that is both faster than a day and faster than we've conditioned users to expect can be called "real time." If you switch from generating reports nightly to doing it every four hours, that's "real time reporting."
