Why does it seem like most people on Quora are arrogant? I get this feeling especially with top writers.

I answered a related, and since deleted question, and squirrelled the answer away here:

What are some aspects of famous Quorans that you dislike? (DELETED QUESTION) by Nick Nicholas on The Insurgency:

There are frequent recurring complaints about Tier #1 writers, those with follower counts in the tens or hundreds of thousands. They are why I make a point of not following them, and have limited interaction with them. They are not intrinsic personality flaws: they are partly Quora Celebrities being the victims of their success (overloaded in Quora traffic), and partly Quora Celebrities being the victims of being the kinds of personalities that end up being followed by hundreds of thousands.
