Balaji Srinivasan had a good take on this recently in his conversation with Tim Ferris. I quote:

"The thing is, I don’t care if something has a thousand retweets, what I care about is if it has two or three independent confirmations from economically dis-aligned actors. This is the same as academia, by the way, everybody’s optimizing citations. What you actually want to optimize is independent replication. That’s what true science is. It’s not peer review. It is physical tests."
