I'm a big fan of MacRuby and have been a big supporter. For those of you who don't know, MacRuby allows you to create awesome Mac OS X apps using Ruby. I'm even writing a book on it - MacRuby in Action.
What's not so awesome is that even though Apple has chosen to include MacRuby in Mac OS X Lion, it's only available as a private framework. This means that MacRuby developers are forced to embed the framework within their applications. It'd be great if Apple could make MacRuby a public framework within OS X Lion.
If you have time, please help us with this and spread the word. It'd also be great if you could open up a radar ticket as well.
