What I am talking about is having a discussion and getting a feel for the person you are talking to.
I am not talking about material information; the kind that could make a stock price soar or plummet.
You aren't going to ever get that from such a phone call.
BTW.....it probably will take more than one such call to get that feel, IMO. And if you go into a one and only call with a confrontational attitude, you might not get any true feel at all.
