Regarding the failure to publicize 10xxx for long distance carrier selection.

The last thing the long distance companies -- or the local operating companies
for that matter -- want the public to do is start using 10xxx to select the
lowest priced caller on a per call basis.  This would lead to:

1) higher billing costs since users would now need multiple long distance
bills each month rather than one.

2)  The possibility of intensive price-based competition, which would
lower profitability.

3) If users were really responsive to price changes, minor fluctuations
in relative prices could lead to major shifts in carrier usage causing
enormous capacity planning problems, both for the inter-exchange 
carrier and for the local exchange carrier with respect to access lines.

In short, there are lots of reasons why no one is talking about 10xxx.
