Again, it's about maturity. Every popular young platform has a relatively large amount of evangelical fervor and a relatively small amount of real-world long-term experience. Java was no different, years ago.
The two Rails programmers I've met didn't know Ruby itself very well. Also both had to bow out of their contract jobs because neither could build a functioning CMS in less than a year. When I talked to them it sounded like they were kicking ass and getting things done, but they were just vomiting buzzwords apparently.
When I started using PHP ten years ago, I inherited an existing project. Two days into it I thought to myself: "PHP is kind of like Perl, but less useful." I guess I missed the PHP hype phase. If it had one.
I've never been a language evangelist. I just solve problems with whatever technology is most appropriate for the case.
