Kevin Systrom and Mike Krieger quit Facebook, six years after their company Instagram was acquired by the largest social network.
The departure of the founders of Instagram came at a time when their idea is gifted as charismatic and over a year with a lot bad reviews for Facebook.
So with all the challenges faced by Facebook's basic application, it will be important to continue to protect Instagram's vision and not allow it to be downgraded. Facebook has long faced the mistrust of its users (and not only), governments, security specialists, and personal data protection activists. 
The reason for the departure of Systrom and Krieger was their dissatisfaction with Zuckerberg after trying for a long time to exercise greater control over Instagram. It is not clear, however, just what was the point that exasperated Systrom and Krieger.
Wall Street does not seem excited about the news, as Facebook shares fell in the morning after announcing the departure of Instagram founders.
It is too early to say what this leadership change will bring to Instagram, a service that has recently reached 1 billion monthly active users. However, below we will dare to mention three changes that we can see very soon, led by Facebook.
More alerts between the two services that will encourage Facebook and Instagram data crossing
One of the sources of tension between Facebook CEO Mark Zuckerberg and the founders of Instagram was Zuckerberg's desire to display more cross-publications between Facebook and Instagram.
TechCrunch Reported Facebook was in the process of adding a shortcut to the Instagram bookmark menu, while Bloomberg he says that some Instagram users were starting to receive alerts when their friends posted photos in their Facebook main application.
Following the resignation of Systrom and Krieger, they are being replaced by a high-profile Facebook executive. This will open the path for the cross-exchange of information between the two services.
Οι λόγοι για τους οποίους το Facebook θέλει να το κάνει, είναι πολλοί. Ο αριθμός των ενεργών χρηστών στη Βόρεια Αμερική – όπου το μέσο εισόδημα ανά χρήστη είναι υψηλότερο από ό, τι στον υπόλοιπο κόσμο – παρέμεινε σταθερός στην κύρια εφαρμογή του Facebook, ενώ είναι ήταν πολύ αυξημένος στο Ιnstagram. Επιπλέον, η βάση χρηστών του Instagram διαθέτει νεότερες ηλικίες από τη βάση του Facebook, οπότε η απόκτηση αυτών των χρηστών Ιnstagram από το Facebook είναι κρίσιμη για την οικοδόμηση μιας βάσης πελατών σε δύο διαφορετικές applications.
More ads in Instagram
Zuckerberg said he believes more users will share content in Instagram Stories instead of the traditional news feed in the coming years. Instagram Stories has so far been very promising, as it has more everyday active users from Facebook's Stories.
Most ads come from Facebook and not from Instagram, but Instagram has more end-user involvement. Facebook will not miss the opportunity to take advantage of more advertisers from Instagram. We should expect more aggression on ads from Systrom and Krieger.
Experiments with them algorithms of Instagram
The new head of Instagram could be Adam Mosseri, who was responsible for Facebook's News Feed. Mosseri was in the past one of those responsible for redesigning Facebook's Big News. This year, it gave priority to presenting content from family and friends instead of content from pages and more.
Instagram's News Feed faces different challenges than Facebook. Fake news is still one problem, αλλά λιγότερο έντονο από αυτό του Facebook, δεδομένου ότι η πλατφόρμα έχει λιγότερους χρήστες. Στο Instagram όμως παρατηρείται μεγαλύτερος εκφοβισμός (bullying), κάτι το οποίο είναι ιδιαίτερα ανησυχητικό δεδομένου του νεότερου της ηλικίας των μελών του Instagram. Πέρυσι η εταιρεία πρόσθεσε ένα φίλτρο με το οποίο οι χρήστες μπορούσαν να προσθέσουν για να κρύψουν επιθετικά comments. A filter was added this year that aims to hide comments that "offend the welfare or health of a person".
At a time when Facebook faces similar toxicity problems, Instagram could be an important field of testing to determine what it takes to develop and maintain a healthier News Feed.
