Does Facebook still need human object tagging data of photos and videos?

I have an idea that would produce human-tagged objects in Instagram pictures and videos. So, much like FB had users tagging faces and using that to inform their machine-learning for facial recognition, this would have users tagging objects.

However, I don't know much about the state of machine learning and don't know if this is something Facebook - or other companies - would still find useful. Would there be a market for a dataset of tagged objects in Instagram photos and videos?
