Regarding the founders trying to ensure ease of access:  I know that, you know that, but we see a trend of making it difficult for people "not in the know."  For example, sector naming.  How do I know if X, Y, or Z approach is North, West, or East?  Or if 12, 21, 14, or 41 center is high/low, east/west, etc?  I've heard controllers get mad at (and yell at -- there's too much yelling on this network these days) pilots for not knowing their internal symbology and nomenclature.  It's a bit ridiculous.

+1 for this statement. It has become a pet peeve of mine, really. As a controller, there is no real reason for these callsigns... I can see exactly which controller has which alpha-numeric ID and the pilot has no use for this information. When flying, it would be tremendously more useful for me to have at least a vague idea of which controller to initially contact when flying in from an uncovered region. Aeronautical charts do not help here either because we do not staff/cover all of the same real world frequencies. I'm not sure when or why this became the norm but I do miss the ol'e E/W, H/L, etc.

As for the few places that still seem to do this, keep it up! You guys rock!
