The main turnoff for me when it comes to Rails is watching other major companies like Twitter completely rewrite their application away from Rails.
Growing pains -- the kind of pains we all want to endure some day. If you are planning to grow, why wouldn't you start with something you know has an end game (like PHP or Java)?
The often cited slowness of Rails, mixed with companies rewriting their codebases, and the flurry of vulnerabilities in the past year has caused me to take Rails less seriously.

I do not like Ruby and have never used Rails, but I feel your conclusion is wrong. Twitter would never have outgrown Rails (at that time they were already wildly successful) if it hadn't been the right (or at least a sufficient) choice for a prototype and initial production framework.
An overwhelming majority of web sites will never grow to the point where they need to drop Rails for technical reasons and some of them will still be hugely successful. If you reach the point where Twitter needed to switch, congratulations, you will able to afford it easily.
