Scoped Thoughts

I've in contact with rails community more frequently lately since I started a new rails project. Before that I was in some Groovy/Grails and Java projects.

Grails and Rails are so similar and both can do basically the same thing. Of course there are situations where one of them will be a best fit for some project.
Besides the technical differences are not so big, the concept of how do things in the framework are not so big either.

The big difference comes in form of community. The rails community is bigger and better than Grails. I don't want in any aspect to degrade the Grails community. They are just like any open source community. But rails community is just different. There are some idealism and they  honor  that in each blog post or each initiative.

A great example is the Rails Magazine. They have a great magazine with actual articles and still offers the PDF version for free (check http://railsmagazine.com/).
Now, Groovy/Grails has a great magazine as well (http://groovymag.com/) but these are not free. The difference in this case is that for Groovy Magazine you have to pay USD $4,99 for the PDF version.

What others differences you see from these communities? What you have to say in favor of Groovy/Grails community?

PS: Please, note that I'm not saying that GroovyMag is wrong in charge. They have this right. I just want to highlight how free and idealist is the Rails community using this example.
