This week, Elon Musk bought a 9.2% stake in Twitter and immediately sent the microblogger's shares soaring by nearly 27%. Musk's investment may be precisely what the doctor ordered for the troubled social-media platform, struggling to enforce its confusing, ever-evolving moderating standards most people find unfair or biased.
Musk does not control Twitter and went to great pains to file regulatory paperwork with the SEC to say that he will be a passive investor. But, as the largest shareholder now, with more than four times the stake of founder Jack Dorsey, Musk has an indirect influence that could change Twitter's direction for the better. With the company’s latest announcement that he would join the 11-member board, this expectation just strengthened.
