Astounds me that anyone is still using that platform after seeing how Musk treated the engineers when he took over.
All six of the speakers immediately said Twitter was realistically the only place you can keep up with the conversation. Having an extensively curated list means that anytime anything breaks (and often a few hours before) you are going to hear about it on X/Twitter.
I would love to know if there is anything even close to the reach of X. It has a lot of problems - but if you want to track breaking news, I can't think of anything else close to it.
