MoBlogs reduce churn

I can't find the Newbay survey but MocoNews has some highlights:

• Mobile Blogging generates an immediate reduction of up to 70% in the propensity of a user to churn.
• Over a 12 month period mobile blog users are, on average, 50% less likely to churn compared with other operator subscribers (1.2% compared to 2.4%). A user that utilizes their mobile blog twice a month has a 50% decrease in their propensity to churn, whereas a user who uses the service four times a month has an 80% decrease.
• Higher usage of mobile blogs greatly reduces the propensity of subscribers to churn.
• MMS was the most popular method of usage for posting to mobile blogs.
