You mean:

Rails for Zombies (http://railsforzombies.org/) Michael Hartl's screencasts/tutorial (http://ruby.railstutorial.org/) Stack Overflow (not a blog, but a really good resource).

I think the number of blogs doing Rails 101 type posts has changed, because there are existing resources that do a great job, and developers/bloggers recognise that.
