I recently asked a question about a technical feature of Ubuntu Core (and specifically its package manager, Snappy). Some users voted to close this, so I think we should start a bigger discussion about whether these questions are fundamentally on/off-topic to help define the scope of the site.
A good point of reference in my opinion is Stack Overflow. Their help center specifically allows questions related to:
software tools commonly used by programmers
Should we consider a similar policy for this site, where questions about tools commonly used for IoT would be on-topic? Would this make the scope too broad or would excluding these make the site too narrow in its focus?
