Anyone know a good collection of SaaS articles like this? We're about to launch our first SaaS service and would love some battle hardened good practices.
As a marketer working with SaaS companies, I would caution you against reading articles like this.
They make big generalizations (free trials are bad!) based on hindsight reasoning and very few data. For every article you find that says you should do X, you can just as easily find one that says you should NOT do X.
With that said, two good sources of information are Jason Cohen[0] and Patrick McKenzie[1].
