Honestly I'd much prefer to see more "comparison" type sites/pages.
Saying "use X for config management" does nothing but create a culture of followers who have no real idea why they do what they do.
Instead, pick a topic and try learning about the pros and cons of the available tools/solutions, and then consider the implications of using it for your environment (or for different types of environments if you do client work for example, and then experiment with it.
