No danger of that. You've read my member bio??
My boss's boss and I used to joke that my ego was so big they had to put double doors on the office so I could bring it in with me. (In that job, a massive ego was a desired character trait). Still, its an uncomfortable truth that has been the source of many of life's difficulties.
I will say that its easier to maintain the illusion of knowledge on forums like this in part because I can choose not to engage on subjects I know nothing about, and in part because I usually have the time to research/check notes before typing - its not like extemporaneous speaking.
