It would be nice to load new post from Instagram with a litte or no delay, so the users can see them in a feed "almost instantly".

I imagine this feature would be triggered in a feed for a limited timespan only.

We want festival audiences to tag and post, and let them view the photos on monitors at a venue. I think this will boost user interaction on a tagged event, and also improve the attention to important information/updates we display on the monitors. Win/win if we can have a nice feature like that.
