The recent disclosure that floppy discs are still in widespread has already prompted one question How long will floppy disks maintain data integrity?. That question, being about the integrity of the format rather than about their usage.
To most users of this site, the current use of floppies in many situations would not come as a surprise. I still help maintain safety-critical systems that receive database updates by burning 27128 EPROMs for example. Every airport I have ever passed through prints its passenger lists at the gate on a dot matrix printer, technology obsolete in offices for a generation.
So my question here is, are questions about using technology that qualifies on this site as retro in a modern setting on-topic?
I mean questions like "Are any industries still using punched cards?". Or are these to be considered off-topic as unhelpful list questions?
