Agree to disagree. In real life, when you endorse a product or service, you are actively putting your reputation on the line. If it turns out great, its just another boost to your already sterling reputation. If it turns out badly your reputation takes a hit. The logical problem with your argument is that you are taking up for a supposedly trusted member with absolutely no reason other than trusted status, and at the same time saying anyone who trusted him enough to invest is, to paraphrase loosely "stupid". so, do you see how you have just discredited your own argument?
No, sorry, I don't. What do you mean by "you are taking up for a supposedly trusted member"?
As for investing, I can't see a direct link between trusting dooglus and an investment into DB or DN. I trust dooglus as a casino owner (still wouldn't invest more than I could to lose and neither should anyone), but I have no clue about dooglus as an investment adviser and I don't know if he had ever claimed to be one or had actually provided any advice other than the assumed endorsements. I don't take investment advice from my dentist or from Oprah either although I trust them in other ways (well, maybe not Oprah). Why does common sense have to be different in an interwebs forum?
