Not everyone has time to read blogs, but I would like to point out one blog that you should read lately: Bear on Business by Dan Caruso. Caruso was an exec at L3 and ICG, raised some money and started Zayo and Envysion. Envysion is a Managed Video as a Service company (don't ask). Zayo is a fiber play with divisions that sell Ip and VoIP -- so a small Level3. (I'm simplifying).
Lately, Caruso is writing about the Sales Process and how Salesforce.com has simplified it for Zayo. Also, how managing Churn and Sales Provisioning means Cash for the company. High concepts, I know, but things you should be thinking about.
