For you.

For the customer with an Internet "mission critical app", being tied  
to a Tier 2 has it's own set of problems, which might actually be  
worse than being tied to a Tier 1.

The Internet is a business tool.  If providers do not meet business  
requirements, providers will not be supported.  Period.

If 200K routes, or more ASNs, or small customers multihoming, or  
stuff like that scares you, find another line of work.  (Hint-hint to  
the v6 fanatics.)
