Ask HN: What are the best resources to read about increasing SaaS revenue?

[csalvato]

I am looking to become an expert on generating SaaS revenue.

I recently found Patrick McKenzie's (patio11's) blog at www.kalzumeus.com/blog, and it has really made me realize that this is something I am passionate about.

Are there any other amazing resources that HN would recommend for learning to get the most out of an SaaS model...or any other SaaS materials that they would recommend?

Thanks!
