A List of Ruby and Rails Tutorials

I'm building a list of tutorials. Some emphasize Ruby, some Rails. I'll add them as I find them, so stay tuned.

RAILS

• Rails Guides, beginner. You build a blog. You can build it out or try to adopt the format to building your own app. 
• Michael Hartl's tutorial.  Considered by most of the people in my community to be the most comprehensive online tutorial out there. 

RUBY

• Robert Sosinski's higher level tutorials. GOOD stuff.
