"I never saw in another technology I worked with, a community so dedicated, that provides you support for any questions and also provides extraordinary material for study"<p>You have never seen that many technology communities then. The Linux Documentation Project dwarfs anything that's "software support". MySQL and Postgres both have larger, friendlier, than Rails. PHP and Perl are both huge too.<p>Those are communities. Not individual blogs, not twitter feeds. Communities. Supporting mature, tried and true infrastructure software that runs the world.
