With the internet error checking should be simpler, but it is actually harder because so many online sources are wrong.
**** is more instantly profitable than error checked news.
The main change is that publications and institutions which used to check scrupulously no longer do.
I feel the article is itself more a product of publicity seeking than rigorous data gathering and fact checking.
The main error with Naomi Wolf was brought about by a combination of bias and insufficient expertise, but it would never have been found by a fact checker - it needed peer review. Errors like this will always occur, and always have occurred.
As an aside, if that article had been published in the UK, it would probably have been flagged as antisemitic because of its choice of initial examples. I assume that's not seen as a potential issue in the US or New York.
