This algo will show photos with more likes on top. I wanna see photos from people and not this hashtagspam pushed crap in my timeline. Instagram fails at catching spam all the time. More likes = more views = more likes. The same problem facebook has right now. I wanna see pics of my follower and not only the "pages" with photographic skills + photoshop + hashtagspam.
It's getting less social and more like magazine-subscription of channels.
