Elon Musk is joining Twitter's board of directors in a deal that prohibits him from buying more than 14.9 percent of the company's stock, Twitter announced today. The news of Musk joining the board comes one day after the Tesla and SpaceX CEO revealed that he had purchased 9.2 percent of Twitter shares.

Musk said he's looking forward to helping Twitter make "significant improvements" and asked Twitter users in a poll if they want an edit button. After about 3.4 million votes, 73.4 percent of respondents had voted yes—or rather, they voted "yse" instead of "on" because Musk misspelled both options.
