There's no way to organically A/B test content on instagram. For influencers and brands, optimized content really makes the difference. This kind of product definitely has a place in Instagram marketing.
Very cool @emreberkst! I just launched something similar called Postable - http://bit.ly/joinpostable. It's not as transparently marketed towards pre-Instagram polling but that's one of the core use cases. Looking forward to checking it out.
