the fact that im always hearing about it leads me to believe its not dead
I heard a lot about that Boeing plane in Alaska too. Indeed, I heard a lot about it than the flight my parents were on that week, which by all accounts, went fine.
The fact that the company insists the product is now called X, but the domain is still twitter.com (x.com redirects to it, not vice versa) and much of their documentation still says twitter too... means something or other.
It's actually a sign that people care. Branding "disasters" have cemented the public's love for lots of brands, including Coke. In a few months, Elon will say that X is the umbrella payments network and Twitter is one of the products on that network.
I love how the media refers to Twitter as "X, formerly known as Twitter" several months later
