A good question is a good question. As long as the questions follow the site guidelines and are "practical, answerable questions based on actual problems" I think they should be welcome.
Wait, you left something out!
Yes, the actual phrase from the help center is: "You should only ask practical, answerable questions based on actual problems that you face." I left out the last part above because it isn't relevant to whether or not a question is good.
For instance, I had no need to update my resume when I asked this question, but with nearly 50,000 views over the past 8 months, I would hope that asking it made the internet a better place:
How Should I Indicate Language Proficiency on my Resume?
The Big Picture
Questions are meant to frame a problem. Whether or not it is framed based on a circumstance I think I'll have in the future, one I had in the past, one that my friend had, or yes, even one from a soap opera, so long as the problem being framed is practical and answerable based on problems people actually face, it should be welcome here.
For instance, let's say I'm a manager, and I see two members of another group having a row over some issue. Their manager handles the issue in a top-down style, but I think it could have been handled between the two members themselves (and that the other manager was premature in acting). If that person posts a question saying, "When should inter-personal conflicts be brought to a manager?" despite it not being an actual problem they are currently facing, we should encourage it.
It is not our responsibility to determine the veracity of a problem being relevant to the person asking, only to decide if the problem is practical and properly framed so that it will get good answers and provide value to future visitors.
So we should all post soap-opera based questions?
Only if you think it's a good practical and answerable question that people will likely face. Asking "How can I deal with my father's first wife marrying my boss while I'm having an affair with him?" should probably be closed in a heartbeat. But if you're watching a Law & Order episode about the 'Blue Code of Silence' and decide to ask, "What is my responsibility to report someone taking responsibility for the mistakes of a coworker?" you may help the many people out there dealing with that type of situation if you frame the question well (using the episode as inspiration for the concept, rather than the details).
Common Sense + Community Moderation = Success
Use common sense, and trust in community moderation. So much of what we do falls under the "I know it when I see it" principle that a blanket ban is probably going to prevent some good along with potential abuse.
If there are specific concerns with a particular user making strings of questionable questions (based on soap operas or otherwise), flag them for a moderator to handle if it is causing the quality of the site to suffer.
In the meantime, Vote Early and Vote Often, and help shape our community with feedback on top of that moderation.
