Agreed.  To sum it up:

It seems that the general use of 'tiers' is based on who carries a
network's IP traffic.
.A first tier provider does not purchase transit from anyone
.A second tier provider buys from a first tier
.A third tier provider buys from a second tier provider and so on...

generally there are a few first tiers who peer at many locations and many
second tiers who are at one or two IXs and have a transit agreement, and
zillions of people who buy T1s and T3s and resell.
