Software as a service, dummy comment

I came across this post, regarding SaaS (Software as a Service) and enjoyed the reading and the explanation of benefits. Question is, what does the writer recommend?

I like this model, for small and large organizations, allowing shared work and cutting costs, especially now, when economy is hurting and organizations are cutting back.

But when it comes to networks, why would an organization outsource its most personal information to external services?

Learning, reading and researching now, hopefully will come out with some good examples for SaaS use.
