just to get all process-y for a minute: a reason that media publlications don't operate at the speed of X or Reddit is that reporting - gathering information, assessing credibility, reviewing source documents, talking to people, checking facts, getting comment - takes longer than "big if true"
making things up is very fast! rushing to judgement takes no time at all! doing even the most basic due diligence on things - especially in an information environment like this one - takes so much longer than you might expect.
