alt Hacker NewsUnfortunately not a luxury for all events.
Some organizations only post information on Twitter, especially those with limited resources. And if their followers are themselves limited in number, then that information is not disseminated.
For example, the Dutch Air Force is currently posting updates on their ongoing airborne exercise exclusively on Twitter: https://www.defensie.nl/onderwerpen/f/falcon-leap
Do you need updates about the Dutch Air Force's ongoing airborne exercise or can you just ignore that exercise? If they weren't posting it on Twitter but were only performing it for a live audience, would you clamor to be part of that audience? Or are you only interested because of the fact it's on Twitter?
