Hats off to Amy Fuhrmeister for finding this and posting it on the class FB wall.
Here’s a crucial comment:
Facebook is great, sure, but Facebook is not a news organization. It does not report, write, research, follow up, or verify news reports. Facebook is a platform on which people share information, some of which is news or news-like. Calling Facebook a news organization is like calling your TV set or your office water cooler a news organization.
I’ve also added a (somewhat grumpy) counterview, which is also a good example of how not to write a web post.
