In 2008, Microsoft attempted to validate the experiment by analyzing the minimum chain length it would take to connect 180 billion different pairs of users in the Microsoft Messenger database. According to Microsoft's finding, the average chain length was hops. In 2016, researchers at Facebook reported that the social networking site had reduced the chain length of its members to three and a half degrees of separation. Dutch mathematician Edsger Dijkstra is credited with developing the algorithm that made it possible for Facebook researchers and others to find the shortest path between two nodes in a graph database.
The impact of blogging upon the mainstream media has also been acknowledged by governments. In 2009, the presence of the American journalism industry had declined to the point that several newspaper corporations were filing for bankruptcy, resulting in less direct competition between newspapers within the same circulation area. Discussion emerged as to whether the newspaper industry would benefit from a stimulus package by the federal government. President Barack Obama acknowledged the emerging influence of blogging upon society by saying "if the direction of the news is all blogosphere, all opinions, with no serious fact-checking, no serious attempts to put stories in context, then what you will end up getting is people shouting at each other across the void but not a lot of mutual understanding”.  Between 2009 and 2012, an Orwell Prize for blogging was awarded.
Both of the Star Trek films featuring Khan, Captain Kirk’s worst enemy, explore the consequences of egoist versus altruist views. In Star Trek II: The Wrath of Khan , we learn that Khan’s murderous anger towards humanity is partly a result of Captain Kirk’s earlier action of marooning Khan and his people on a then hospitable planet—which later suffered an environmental disaster killing most of Khan’s people. This is a clear illustration of the ethical egoist’s claim that trying to act in others’ interests may be immoral. Furthermore, Kirk’s failure to check up on Khan on the planet suggests that Kirk was not really acting altruistically, but rather egoistically, supporting the views of psychological egoism. Meanwhile, Khan believes that he has a natural right to dominate, based on his superior intellect and strength, a view commonly associated with rational egoism and Ayn Rand. Of course in the end, Mr. Spock demonstrates altruism by sacrificing himself to save the rest of the Enterprise crew, repeating an idea clearly meant to prove that altruism is more rational than egoism—“the needs of the many outweigh the needs of the few.”
