To assume that some languages must be poor languages because of the "choice" is more than a little short sighted. This is like saying that one car is a better one than another because of the color options. Just because you like one car better than another because of the color, doesn't mean it's a better car, especially for someone else that doesn't care about the color, but the use.
Clearly, some languages are better suited for certain tasks, but they can all perform mostly the tasks, and many just as well as the other, provided you compare one proficient programmer in one language to another in another language.
I'm sorry, but you're just showing ignorance about programming if you claim that they "mist be simple to read and easy to learn". The famous "C Programming Language" book by Kernighan and Ritchie is ~190 pages, without the attached reference manual, which only brings it to a total of 258 pages. It's short, easy to understand and one of the most powerful and most used languages in the world for the last 30 years,
The Perl language is painfully easy to use and understand. Perl, like C, and like PHP, Ruby, Python, C++, and any other language, can certainly get involved and complex, but only if you make it complex. Nothing in any language is difficult to grasp. If you don't have the mind for it, and thus think it's too complex, then you don't understand it, and you not understanding it doesn't make it a poor choice for someone else.
In fact, for web applications and data processing, especially working with text (which 99% of the web related files are made of), it's a superior choice. Again, simply because you don't agree it's easy or readable or non complex, doesn't make it so. I should know, I've been coding in all of these languages for years, and I'd certainly know if one was that much more complex over another.
I don't recommend anyone listen to this guy. It's ludicrous to claim that Perl should be avoided. Notice I'm not bashing any language, because they are all worth learning, and Perl is certainly common and powerful enough to justify. Just knowing only Perl would provide you with the tools to do anything anyone could throw at you that can be done in any other interpreted language. It's sad to see people making claims about programming languages, arguing and flaming about it, when they have no basis for doing so.
