Very interesting and thought provoking questions! I myself am not big on insert note collecting like I was with X notes years ago.
While I don't have much to say in regards to the questions posed, I would however advocate a system that easily identifies replacements and is more user friendly than what we have now. Personally I think it's too confusing and dependant on a handful of dedicated Collectors to sort through and analyze. If they grow weary of the brick hunting/researching then someone else has to take their place and that could be difficult indeed.
Point is that alot of work goes into discovering inserts and the BOC likely isn't obligated to tell us anything so we're left at their mercy. They know there's a large market for replacements, errors, inserts, radars, rotators, etc out there and it isn't their job to cater to us. They just make a product that we're infatuated with.
If we're going to see any major changes it will have to be with the next series in 2011 onwards. This is where we can have the most influence, but it wouldn't hurt to continue the great relationship CPMS members have with the BOC and hope for a few more treats along the way.
I am indeed fortunate to be able to attend the CNA convention in part on Saturday for a few hours in the afternoon(between 12 & 5pm) if anyone wants to grab a coffee/snack at some point in the hospitality room.
