Am a phoenix/node developer. not offended.

Rails certainly has its strengths. If speed to knock out a working app was my #1 prereq, rails has better abstractions and drop-in libraries to get something off the groud fast. Its probably your best bet for knocking out a CRUD mvp.

Not sure why would I, a "Golang person", be upset (also a Ruby person, even though I've never used Rails, lol).

Rails is a fantastic choice for its usecases.

RoR is fine... as soon from Rails 4, I need to get back in.

Totally.
