There is no better way to evaluate a framework than seeing how others have used it in real world projects. With that in mind, I have created a wiki page where we can highlight adopters of Sapphire and how they are using the framework.
I have seeded the wiki with some initial content describing how Oracle is using Sapphire.
If you are a current adopter, please consider contributing a section. You can promote your product or project a bit while benefiting others in the process.
Here are some other ways that you can show your support for Sapphire:
1. Click on Ohloh's "I Use This!" button, give Sapphire a star rating, write a review, etc. Make sure that you've entered your locale in your profile, so that you can be placed on the world map of Sapphire users.
