I have no choice but to short Tesla stock, no matter how much I like the technology or company. Elon's 30B stake he put up to buy Twitter will have to be sold when the Twitter revenue dries up - and with advertisers and big names leaving that path is inevitable. He really doesn't realize that once you lose market penetration, your done forever no matter how nice you make it. Myspace taught us that. They had a beautiful revamp once upon a time, but it was too late. Facebook ate it's lunch. Same will happen here, only worse.
