I would guess that Quora's algorithm could be gamed pretty easily by having an employee leave a positively-biased answer to a question and then having a bunch of other employees upvote the answer.
The company could even have an employee seed the question, then have other employees answer and upvote in order to bury other questions that have negative responses.
Basically, Quora appears to tolerate quite a bit of spam, which would make it hard for them to be an authoritative source on anything other than "how do I game Quora's algorithm?" (since obviously whoever's answer is highest-rated has won ipso facto).
I used to frequent Quora and stopped specifically due to this. Leave a few answers on popular topics, especially about apps, and your inbox is flooded with requests to answer questions like "Is it true that X company is the most amazing and affordable software development outsourcing service?" and "Why is Some_Random_App much better than Popular_App_That_Our_App_Copies?". Sometimes they were brazen enough to post questions about X app with names like XMary or XJohn.
