Ok, when i meet a Fluke or Tektronix or Siemens or Norma engineer i will  
tell them that they are doing it all wrong and square pins are not  
acceptable for test pins. I'm not sure if they will be insulted when i  
tell them they are ghetto technicians ;-).
I'll just tell them the great Tony Smith has said so, and he must know  
after all, i'm sure they'll immediately see their folly.

No many people will indeed not have seen a pogo pin, because they are  
utterly useless for anything other than series production testing. We were  
talking about test _pins_, not _pads_, you do remember that?

I care enough to respond because i can't stand it when people write  
nonsense and insist on it without giving any decent reasons, let alone  
proof.
