The guidance when voting to place on hold as primarily opinion-based is:
Many good questions generate some degree of opinion based on expert
experience, but answers to this question will tend to be almost
entirely based on opinions, rather than facts, references, or specific
Your question why there is even a POSTgis day was titled:
why there is even a POSTgis day
Which ones are exactly Gis Day's principles, statements or
characteristics that POSTgis Day people disagrees with? To what degree
are both events celebrating exactly the same, and to what degree are
they different in a such a manner that they are separate events?
Kindly provide pointers to some expert, authoritative or in depth
discussion or reflection on wich your answer is based
I did not vote on your question but, if I had seen it then I would probably have voted to place in on hold as either:
- too broad because it asks more than one question; or
- primarily opinion-based
I think the latter (the subject of your question here) would be perfectly valid because you ask potential answerers to specify what they disagree with and indicate that you seek a discussion.
GIS SE is not a discussion forum; it is intended for focused Q&A. Any time a question strays too far from describing what you want to do, what you have tried and where you are stuck I think you run the risk of it being poorly received and likely to attract down and/or close votes.
Your profile indicates that you are relatively new to the site so if you have not already seen it, I would recommend reviewing Asking good Questions for GIS Stack Exchange? which is linked to from our Tour via our Help Center.
