ISP Planet has an article reviewing Mike Cassidy's session at ISPCON about ways to increase your business through services in 2007. Mike has been pointing out that all the opportunity for ISP's falls in the space where you cater to small businesses. It is a good read, especially as you plan for 2007.
The keynote was a panel representing 4 differing business plans: Dane Jasper from Sonic.net as the DSL provider; Jonathan Snyder from KeyOn, a wireless provider; Dan Hoffman from M5 the VoIP Provider; and Rich Bader of EasyStreet, a managed service provider.
Lots of ideas to read and review.
