These screencasts are awesome

A great encore by a master teacher

Something you just can't get as well from a book

The new screencast series got me to a whole other level of understanding

The equivalent of a packed 2 or 3 day Rails course at a bargain price

The best tutorial since K&R

The best Rails tutorial on the planet

Learning has been sped up 3x faster!

The #1 place to start when learning Rails 3

Ruby on Rails Tutorial is the best!

Woohoo! This is some fun coding with RoR…

Very detailed and hands-on Rails tutorial!

I love the writing style of the Rails Tutorial

Awesome book—Thanks!

A precious Gem

Rails Tutorial Rocks!

The best introduction to Rails I've ever seen

Impressive

Great Explanation of Version Control, Hosting and Testing

Incredibly useful
