Ask HN: Gemcutter or Google Code for Ruby Gem hosting?

I don't know who is behind Gemcutter or how it came to be that I woke up a few days ago and Gemcutter was the newly appointed hosting service for Ruby gems.

Was there a vote?

Who decided this?

How did they make that decision?

Here's my thought and tell me if this crazy.

Google is, by some accounts, a well funded company which is likely to be around for a few years to come.

They also happen to provide free code hosting for open source projects.

You see where I'm going with this? Yeah, why not host Ruby gems on Google Code!? Crazy? Please tell me why. Thanks.
