Yes, it is. We are mostly professionals here and understand the limitations of technology, specifically when talking about latency and implementations ranging from websockets to long polling. We look past these minutiae and get to the real subject of getting data to the user as soon as possible. Generically, this is referred to as "real time".
I actually wish we called this something else like say "persistent". Real-time systems have a very specific meaning for many people and while yes we all get it, it is probably a point of distraction for a lot of people to hear this term constantly misused.
