Latest local example: How to portray 'lifestyle' in an app logo
The only similar question I could find in GD Meta is Is "what's the best / most effective / your favourite logo" on topic? but it's not exactly the same. It's about visual representation rather than "the best for".
These type of questions have been discussed (and decided to be rejected) in UX meta: https://ux.meta.stackexchange.com/questions/629/is-it-time-to-put-an-end-to-icon-for-x-questions
I myself asked a similar question regarding a visual representation for an icon ("Time Range", which is rather a complex thing to show in a single icon) and had it closed. I'm not sure how they are treated in GD generally speaking, but I felt there was a limbo in stacks for them, when some are actually closely related to graphic design and to usability. So I'm wondering what's the right approach for us here.
Edit: I remember seeing some very creative discussions here about how to represent concepts in a new way. If valid questions can be answered here, should the UX people be redirecting theirs to us?
