I’ve looked at a number of open source Rails apps that can be used as a starting point for a project (see the post Survey of Rails Example Applications).
Since I’m considering starting a project using Merb instead of Rails, I wanted to review a collection of open source Merb apps. I didn’t have to look any further than the list of Open Source Merb Apps on the Merb wiki. The author even said, “Sometimes staring at code can be a good learning technique in addition to tutorials and documentation.”
