Instagram update includes ability to edit typos
Instagram has also improved its Explore feature, which helps you find people that you want to follow. The Explore icon is now a magnifying glass. When you open Explore, you will see a pair of tabs, Photos and People. The former remains the same as it has always been, a grid that scrolls revealing pictures and video.
What has changed is the People tab, which now recommends other people whose Instagram account you might find interesting to track. The more engaged you stay with people you follow on Instagram, the longer you stay on the app. The longer you stay on the app, the more ads you view. And the more ads you view, the more money that goes into Facebook's vault.
