Allow me to attempt to clarify then.

Telling people to NOT write on the internet about stuff they are passionate about is not only a waste of time, it has proven over and over and over again to be terrible advice.

Ben, for example, was passionate about points and flying for free. He openly coveted the business and first class lifestyle. I'm sure people told him to quit wasting his time obsessing on the Internet, get a job, stop his jealousy, grow up, etc. And yet he persisted. And now he gets to live the business and first class lifestyle that he used to openly covet.

Same thing with Perez Hilton and his obsession with drawing rudimentary genitals on the faces of celebrities.

And even if one does not get rich quick obsessing about things on the Internet, such obsessions still have utility in the form of wikipedia where 'losers who need a job' have created an open source encyclopedia. Or FlyerTalk, where a bunch of 'obsessives' 'waste their time' talking about planes and hotels and points and miles...and in doing so have created an irreplaceable resource.

Make more sense now?
