Maybe. If Ruby / Ruby on Rails is a good language for web-development, easy for beginners to learn, the community is helpful, beginners feel welcome, and experienced developers invest in teaching; you'd expect to find a small army of 'just get it to work' developers knocking out small projects and charging too little.

I'm ok with that. Small projects get done. Not everyone needs a $125/hr consultant. Some of those projects will grow and need more experienced developers. All of those beginner developers will gain experience. Some of those beginner developers will continue to grow, learn testing, learn better software design principles and start contributing to the community.

If Ruby on Rails has, or were to have, a small army of beginner developers writing poor code on small projects and charging too little for it; I think it would be a healthy thing.

Disclosure: I got started as a Rails-first-language developer and have loved every second of it. And I try to get new people started with web-development using Rails and hope to see them get their first small projects that they can write bad code for and get paid anything for.
