4chan is archived. Screenshots exist.
4chan archives can't be trusted as permanent sources because a site for them goes down every other month. They also often only go back so far, leaving you with no source.
Searching them is even a bigger pain. And you can't search for screencaps.
The majority of memes do not come from “not nice” places anymore.
So ED as a source is then bad because…?
It fits the standard apparently.
If an ED article happened to have information that could not be found anywhere else, that would mean they do not have a source to begin with.
Because the NY Times is just dying to document baby rape or the average shitty furry that has an article there. There are topics other sites intentionally steer away from.
You would have to follow their word by blind faith, which would be counterproductive and make the whole process pointless.
There is a point where you're going to have to, nothing is perfect. You then write "According to X and Y…" at which point it's clear our direct knowledge is limited.
Plenty on the internet is saved, but plenty is lost forever. You won't always find back a direct source, at which point you're going to have to trust someone else's research.
You should become a professional critic, just calling everything that is researched bullshit until they show you datasheets.
Why is a middle man necessary?
This point can be applied to every source section on entries. Why is Wikipedia or are Wikias necessary?
Keep ED.
