What Elon Musk's seat on Twitter's board could mean for its users

Tesla CEO Elon Musk now has a 9% stake in Twitter and a seat on its corporate board of directors, raising questions about how the billionaire business magnate could reshape the social media platform. As Twitter's biggest shareholder, he has the ear of top managers.

"Through conversations with Elon in recent weeks, it became clear to us that he would bring great value to our Board," Twitter CEO Parag Agrawal said on Tuesday morning.

The "friendly move" will likely "lead to a host of strategic initiatives" both in the near- and long-term, said Wedbush analyst Daniel Ives said in an April 5 report.
