Expertatitis 

expertatitis is a kind of mental disease where people affected with this are very likely to spit out a bunch of useless stuff around their answer, trying to validate & applaud their own expertise! you can find people affected with this on quora all the time, where you will look for an answer, and find these people's answers, but you will need to read through a bunch of useless stuff to find what you are actually looking for. These are the people who give 1 line answer in 10 lines

bro, I hate quora sometimes, because most of the time, I see answers from people who have Expertatitis!

Half of the experts on quora are suffering from Expertatitis!

Expertitis. 

An affliction that causes considerable problems for people who become so expert at their chosen line of study or research that no one can understand those who have expertitis.

I've become so expert at dealing with highly specialized cases of wrongfully arrested cases that I have difficulty teaching my craft to others. That's Expertitis.

That's problematic because the truth is that a law degree is of no use to any would be expert who wants to specialize in the sort of cases that I deal with.

I have a 100% success rate, but "Expertitis" makes it difficult for me to understand why amateurs can't do what I do.
