The wrong lesson is being learned. It's not just reddit or 4chan or GAF or the internet or CNN. It's the general desire to know everything as it breaks and to become an instant expert on the story and to feel like you're helping and to feel like you're a part of something and to have to know the next shocking twist. It's human nature to get excited about this stuff, but it's our failure that we don't conquer that nature by calming ourselves and wait for actual news to come out. If people really want to learn a lesson from this, it's that they should check out entirely, advocate slow journalism, don't reward groups for breaking up-to-the-minute details or indulge in them, and read long-form summaries at the end of it all.
Not likely.
