The game has changed — and most creators still don’t know the rules. Instagram no longer runs on a single algorithm. It operates four distinct ranking systems simultaneously, each with its own logic, preferences, and path to explosive growth. Miss even one, and you’re shouting into the void while your competitors capture audiences by the thousands. Here’s what separates those who break through from those who fade away: understanding the six core signals Instagram’s AI tracks across every single post, Story, Reel, and Explore appearance. The Engagement Hierarchy Nobody Talks About Not all interactions carry equal weight in Instagram’s eyes. A like? It barely registers — a digital nod, forgotten within seconds. A comment suggests deeper investment. But saves? Shares? These signal something Instagram craves: content so valuable that people bookmark it for later or pass it to friends. Think of it as Instagram’s trust ladder. Each rung climbs higher in algorithmic value: Likes: Acknowl...

The fatal shooting of Alex Pretti, a 37-year-old ICU nurse and U.S. citizen, by Border Patrol agents during a Minneapolis immigration protest has triggered rare bipartisan condemnation of the Trump administration. Video evidence contradicts federal officials' claims that Pretti brandished a weapon—footage shows him filming agents with his phone before being tackled, with officers removing a legally registered firearm from his waistband seconds before shooting him. Federal and state authorities offer starkly different accounts. Homeland Security Secretary Kristi Noem labeled Pretti a "domestic terrorist" who approached officers with a weapon, while Minnesota Governor Tim Walz called this "nonsense" and urged officials to stop "smearing" the victim. Minneapolis police were blocked from investigating the scene despite obtaining a warrant. Republican senators, including Thom Tillis and Lisa Murkowski, are joining Democrats in demanding a thorough, independ...

Hours after his address to the World Economic Forum in Davos, Switzerland, on Wednesday, President Trump said he had reached a framework agreement with the leader of NATO over the future of Greenland.Credit...Doug Mills/The New York President Trump declared Wednesday he had reached a framework agreement with NATO Secretary General Mark Rutte regarding Greenland's future, backing away from earlier threats of military action against American allies over the Arctic territory. The announcement followed NATO discussions in Brussels about granting the United States sovereignty over small pockets of Greenland for military bases—a model similar to British sovereign bases in Cyprus. Three senior officials confirmed these talks occurred among alliance military officers. However, NATO emphasized that "negotiations between Denmark, Greenland, and the United States will go forward" to prevent Russian and Chinese influence in the region. Trump's concessions marked a significant ...

President Donald Trump greets Norwegian Prime Minister Jonas Gahr Støre, upon his arrival at the White House, Thursday, April 24, 2025, in Washington. Alex Brandon/AP President Trump claims his push to acquire Greenland stems from not receiving the Nobel Peace Prize, telling Norway's prime minister he no longer feels obligated to prioritize peace alone. In a Sunday message, Trump criticized Norway for the perceived snub, asserting that "Complete and Total Control of Greenland" is essential for global security. He announced escalating tariffs—10% starting February 1, rising to 25% by June—on eight NATO countries that deployed troops to Greenland for a Danish Arctic exercise. European leaders condemned the tariffs as undermining transatlantic relations and risking a "dangerous downward spiral." Trump questioned Denmark's ownership rights, noting boats landed there centuries ago. The Nobel Committee, not Norway's government, awards the Peace Prize. Denmark ...
