Monitoring of local ARTCC or Approach frequencies for traffic, I've found is not worth the trouble.

So you did not hear ATC communicating with the C421 about the conflict? Was there any way for ATC to contact you by radio?

I was not monitoring ATC frequency. It was in ARTCC airspace and the frequency was not obvious unless you have an IFR map or are "in the system". There was another glider a mile or two away with a transponder, so ... I suppose it would have alerted me to increase my scanning for traffic. But, there is no way to know which direction to look and that is the basis for my original comment that monitoring ATC frequencies doesn't help that much for collision awareness. I was just lucky that my scanning caught the C421 while in a right turn, but the PowerFlarm PCAS went off a second or two later.
