Not only did you write this article in an unreasonably sarcastic tone in response to a blog post that isn't the best "intro to Rails", but it's also clear that you clearly lack the programming experience to say that installing Rails is "insane".

> If you want to use Linux, sorry, you’re kind of on your own.

Rails does run best on a Mac, and there are reasons for that. However, it can also run on Linux or Windows with cygwin.

> Open the Terminal. Don’t worry about what it is or where it resides on your computer.

This is where I seriously doubt your ability to have a professional opinion on that. If you've never used the terminal and you're so unfamiliar with it then you're scared the author might be using an unfamiliar program, then how are you expecting to get started with a web framework that works exclusively out of a command line?

> Install a package manager. What’s that, you ask? Don’t worry about it!

Once again, if you don't know what a package manager is, maybe you should learn about things like this first- RVM works wonderfully with Rails gems, but you don't appear to have anywhere near the amount of technical knowledge to know that.

> Now quit the Terminal and re-open it for some reason.

Yes- you have to restart Terminal before using newly installed frameworks. This is basic terminal knowledge.

> I want to see people programming, and learning to program.

Excellent! Yes, the article you responded to isn't great, especially if the reader has little programming knowledge. But slamming Rails because it requires some basic skills around Terminal is inappropriate and reflects upon poor technical awareness.
