Patrick Pleul | AFP | Getty Images Elon Musk is tweeting on Twitter again. This time, he has come up with a series of suggestions for Twitter Blue, the social media giant’s subscription service. They include price reduction, dogecoin payment capability and ban on ads. The billionaire CEO of Tesla and SpaceX – who now owns 9.2% of Twitter – is a productive Twitter user who often drives the market with his tweets. He was named to Twitter’s board on Tuesday and said he was looking forward to working with the board to make “significant improvements to Twitter in the coming months”. Launched in June, Twitter Blue is the social media giant’s first subscription service for those wishing to pay for exclusive access to special features – such as Tweet Undo, custom Twitter app icons and bookmarks. In a series of tweets on Saturday, Musk suggested that there be no ads and that the subscription price be reduced. “Everyone who subscribes to Twitter Blue (ie pays $ 3 / month) should receive an authentication mark,” he wrote on Twitter. “The price should probably be ~ $ 2 / month, but paid 12 months in advance and the bill does not receive a check mark for 60 days (track CC billing reversals) and is non-refundable if used for fraudulent / spam mail “, he said. “And not ads. The power of companies to dictate policy is greatly enhanced if Twitter depends on advertising money to survive,” he added. Musk also suggested that pricing “should be commensurate with affordability and in local currency.” “Maybe even a payment option at Doge?” suggested, referring to cryptocurrency. Twitter has not yet responded to CNBC’s request for comment. Twitter Blue is only available in the US, Canada, Australia and New Zealand. The undo feature allows subscribers to change their tweet before it goes live. It is not an editing feature that Twitter users have often requested. “It’s not an edit button, but an opportunity to preview and review your Tweet before it is published for the public to see,” the company said.
