Is Fluther a subject of downgrading of Quora?

I know this question may get modded and/or stir some controversy here, but I mean no ill will, just ask this out of curiosity, and I have fully steered myself for seeing this question (or possibly me) get modded.

Inspired by some recent events about Fluther/Quora.

There have been some questions asking about Fluther in comparison with Quora. And all of them have the same content: why does Fluther not have things Quora has. I also went to Quora for some research on Quora’s opinion about Fluther, and came to a conclusion: Quora openly downgraded Fluther in their website.

Why does Quora do this? Is this the way they promote themselves? And if so, why Fluther, and not other Q&A sites?
