Sort of like moving your smelly dumpster in front of your classy restaurant to increase the dumpster's reputation.
This is a good metaphor, so let's run with it.
It would certainly improve your reputation among raccoons.
What are the raccoons in this metaphor? presumably the idiot demographic
Yeah, something like that. Idiots, trolls, etc.
And now, the restaurant is on fire, while the dumpster is fine...
Which is what makes it a stupid idea. Credibility is hard to get, easy to lose. It seems obvious that the poor reputation of Buzzfeed would bring the news part down rather than the news bringing the rest of the operation up.
