To Ruby or not to Ruby

I was wondering if i should start tinkering with ruby to see what sort of framework it was. Then i read some items that suggested that it was still in its infancy as a technonolgy. Poor speed, not enough documentation.

I mean its sounds good to write less code, and have db mappping handled for you, but at what cost. I have spent years writting jscript asp with variable types, but the amount of errors that you miss without compile time and type checking support is painful. I prefer to let Visual Studio do the meanal tasks like remembering method names and type checking.

I think i saw somewhere that threading and internationalisation were issues, so it doesn't sound like an enterprise framework.
