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!
