Our questions deal with interpersonal interactions.
It would naturally be a bad idea to bring up the real names of the persons involved when writing a question. Some OPs overcome this using friend, friend's friend, person A, person B etc. which is difficult for us answerers to use. It's also taxing us when it comes to using gender pronouns like he, she.
I have, in some cases, requested OPs to add placeholder names like Alice and Bob, or whatever they see fit. Although that may not have improved the questions much, it would make it much easier to understand who's who and what's what in the question. It will aid comprehension, that is.
Should we encourage users to use placeholder names more often? Do you find any harm in letting this be a thing here?
