So here’s a pet peeve of mine: date display format.
Since early on using the computer I have started using the YYYY-MM-DD format to display dates, and especially on file names. It is particularly useful when organizing my photo collection. I never knew of the ISO 8601 standard. As files by default are sorted by file name, I figured this way the files will always be displayed in chronological order. Telling the computer to sort the files by date doesn’t always work.
Basically, it is one of those small things that make your life easier.
Most people I know [... EHEM], however, use DD-MM-YY. While arguably more “natural”, it is confusing when you open a folder and the files are all over the place. So you have to go through each file one by one to find the one you are looking for. Worse, some people don’t even have a consistent way of displaying dates and naming files, and don’t even know how to use CTRL-F!
