I didn't say he was a good person. But it's obvious that he's not incompetent and that he's just trying his best to salvage his investment. The idea that he is intentionally driving Twitter into the ground is beyond ridiculous.
According to himself it has fallen 50% in value since he bought it. If he just wanted to salvage his investment he'd tweet once a week about about features or metrics. As it is he spends a lot of his time shitposting and making facially absurd claims.
Right...and I'm saying that if he tweeted less and delivered more, he'd be taken more seriously than he is. Hype/salesmanship is part of business, but in the case of SpaceX and Tesla, they're delivering bespoke and high-end manufactured products. People are willing to wait for infrequent product delivery while tolerating sometimes-fanciful claims of great potential.
Twitter is different because it's a real-time mass communication platform, so the hype is received and processed differently. And outside of his fanbase, few people seem impressed with the changes as manifested so far and this is reflected in the response of advertisers.
Long tweets seem to work OK and offer a clear, obvious user benefit. I'm having difficulty thinking of any other examples.
