there, now you’re all caught up

Note how your quick summary skips a lot of information and views, that give people context on what happened. For example:

• how power users were gaming the system, and that the userbase was already pissed, even before Digg v4;
• what's wrong with Digg v4, and why users hated it so much;
• the pressures that caused v4 on first place;
• the state of Reddit (and Twitter, and Facebook) when the Digg exodus happened;
• how people organised that mass exodus off the platform;
• how the news back then covered Digg's downfall;
• who's Kevin Rose again? (I bet that plenty people don't even know who Kevin Rose is, let alone his role on Digg.) etc.

And yet it's unreasonable to expect anyone to remember everything about the events. And we [people in general] shouldn't even trust anyone in specific to begin with, because everyone [including you and me] is a bit biased and will cherry-pick a few details and ignore others. For that we'd need a central repository documenting the downfall of Digg, preferably from multiple users' PoVs. I think that this is important, because better knowledge of the past allows us to guide better our future actions.

Same deal here with Reddit.

Fark and Slashdot were always kinda centrally controlled. During the heyday of the internet frontier they were fresh and hilarious, but they never attracted younger people because it was just the same jokes over and over. And without building younger communities they died of irrelevance.
