Let me rephrase. I am proposing that (barring very specific requirements which webdev doesn't justify) there's no such thing as a "good PHP developer". A good developer is a good developer, period. A good developer will learn a new language in a reasonable amount of time and will be able to be productive and write good code in it. A PHP-only (or X-only for that matter) developer is, by the definition above, not a good developer. So why restrict oneself to some random pool of X-only people?
