I've seen quite a few comments (on HN and elsewhere) since all the "fake news" buzz started saying essentially "Facebook needs to stop pretending they aren't a news company. They are where people get their news, and they need to take responsibility for that"
And I completely agree. Whether zuck wants to be in the news business or not, he already is. Might as well do a good job of it.
No, they're not. Facebook is a news aggregate. They are no more in the News business than I would be if I wrote a script to scrape news web sites for articles to read myself.
The confusion between actual news sources and information aggregates online has caused this "fake news" crisis in the first place.
