GigaOm post on Ethernet Exchanges

My first post for GigaOm is up on the Broadband section. It is a high level explanation of what Ethernet Exchanges are and why they represent a shift in communications.  We should really stop calling it telecom.  Ethernet exchanges can be thought of as truly open wire centers, like an old school telco Central Office, but where you bring an Ethernet connection rather than a twisted pair copper connection.
