Sorry, no deep analysis of 'talking nonsense' to follow. Just an observation.
An old (circa 2006) thought found while reading on Epinions dot com:
"I originally had a lot more to say, but a lot of it makes less sense than what I just typed, so I should just stop here."
Damn it people..!! That is why we read on the Internet: to find nonsense..!! Quit self-censoring your thoughts..!!
Talking nonsense, posting nonsense . . .opposite sides of the same coin...
