Also, I'll just point out that there is certainly a religion of RoR unlike that of any other web framework. Thus, whenever someone makes disparaging comments, some RoR fan takes serious offense. You seem like you were personally offended, for example.
Frameworks have their own strengths and weaknesses inherited from the languages used to build them.
So quit the hating, please I don't get why RoR dudes(not all of them in fairness) love to bash hackers using other languages or frameworks. Although blogs like this tend to bring out alot of passionate if not misguided individuals.
I say pick your tools for the job.
Rails is great, though, the only things that seem to come close are the Python frameworks, and I think at that point it comes down to a question of taste, and I think I like Ruby more than Python (even though I've used Python since...'99? Before it was popular in any case).
That being said, however, the seemingly constant attacks by every person who takes it for a spin and doesn't love every aspect of it does get pretty irritating.
But, I suppose, as long as they're being constructive, no harm done.
