You've got *your* routes, which could represent enough data to warrant  
settlement free interconnection.  e.g. Facebook (on peeringdb) claim  
5-10Gbit of traffic. Yahoo 100Gbps plus.  They can only offer their  
routes, but ISPs are regularly happy to peer because it represents  
enough traffic to be worthwhile.  Peering also (usually) reduces  
latency between end users and content, which improves performance for  
mutual customers.

Data passing on an ISP networks may cost the network some money, but  
it only exists on their network because they're billing someone, and  
letting them dump traffic onto the network :-)  They have the option  
of passing it to a peer for free, or passing it on to an upstream ISP  
for cash.  The economics that dictate what's viable are very involved,  
but if you're growing it's worth trying to understand them.
