I'll assume you're not kidding and answer your question. Yes, of course people still use RS-485. It's not RS-232 over longer connections though, it's just a different type of serial driver for a UART interface (i.e. it is equal to RS-232 but handles the line driving differently). One such difference is the use of balanced A/B communication lines instead of +/- lines used in RS-232, which yes, gives it better reliability over longer distances.
Specifically the popular Modbus protocol runs over RS-485 and it's used extensively in industrial control systems. DMX, which is still used extensively in the theatrical/concert lighting world is also based on RS-422/485, though there are some differences.
