As is common on many SE sites, I see opinion-oriented questions that are off-topic. This is an example of one, here, I think.
Whereas I think questions like this ask for an answer that demonstrates a design trade-off solution. In this latter case, there are specific criteria that can be used to argue beyond opinion.
Are we more-tolerant of opinion questions here, or do we keep to the non-opinion flow of StackOverflow, etc? Where is the line for us?
