The important part of the phrase was not just "Q&A", but "code Q&A".

One issue that brings is the width of screen needed to view (or write) code - and the screens of mobile devices are generally far too small for that purpose.

Another is the kind of typing that is needed to write code - which is something that the "keyboards" of mobile devices are usually very bad for.


I haven't heard of anyone coding on (rather than for) a mobile device before, and despite the improvements in those devices in recent years I don't see that changing... and unless it does, I don't see the benefit of being able to access the forums in that way.
