X.com probably makes sense in the assumption that he turns Twitter into a WeChat clone as kinda 'everything app' which would obviously fail. But as 'everything app' X is kinda a strong brand IMO.
I'm not sure. It's very tech-nerd (like me) and tech-bro oriented. The logo as well, I'm pretty sure it please the aestetics of tech bros, but at least some nerds/geek find it stupid, and I'm pretty sure it doesn't bring a lot of new female users.
Twitter was already one of the most male-dominated social media (especially outside the US), I think it would be interesting to see the evolution now that this became X. I'd bet a huge majority of new joiners are male (due yo the branding change), and a small majority of 'leaver' are female.
If "X" can transition to a WeChat clone, then maybe, until then it's a shitty brand. The media always needs to present is as: "The social media platform X", "X, formerly Twitter" or "Elon Musks X". The last one seems to indicate the Elon Musk is a bigger brand than "X".
