With instafall you can follow any user, hashtag or media flows in a specific location. In addition you can catch medias which are shared near by you in a circle of 1-5km.
From the left sidebar, click + icon, "add column" window will slide right. From this window click third icon(under # icon), then click add nearby. P.S. You have to give permision for sharing your location with app, when the browser asks. Hope you enjoy :)
Can't seem to find that (can find "nearby"..)
