Why don't ISPs peer with everyone?

I manage a network that's primarily a hosting network.  There's a similar 
hosting network at the other end of the building.  We both have multiple 
gigs of transit.  We don't peer with each other.  Perhaps we should, 
because the cost of the connection would be negligible (I think we already 
have multiple fiber pairs between our suites), but looking at my sampled 
netflow data, I'm guessing we average about 100kbit/s or less traffic in 
each direction between us.  At that low a level, is it even worth the time 
and trouble to coordinate setting up a peering connection, much less 
tying up a gigE port at each end?

100kbit/s at <1ms is better than 100kbit/s at > 1ms.

We are hosting as well and some of our top 25 ASNs are other hosting networks, YMMV.
