dumber than a box of hair said:And you cannot rely on call-ins or "me and all my friends" for any kind of statistically reliable data.
I'm pretty sure you are right about that. I usually take them with a large grain of salt. The folks who call in are a lot like the people, like us, who post on this and other message boards. They may be “interesting,” but not necessarily typical.
Thanks for the info on the PPM.
