I was reading the following article: Great Hackers

The following part grabbed my attention:

"When you choose a language, you're also choosing a community. The programmers you'll be able to hire to work on a Java project won't be as smart as the ones you could get to work on a project written in Python. And the quality of your hackers probably matters more than the language you choose. Though, frankly, the fact that good hackers prefer Python to Java should tell you something about the relative merits of those languages."

I would like to apply his advice on a commercial web application I am building (I am a strong believer in culture and community), yet this article was written in 2004, and python has increased in popularity in the recent years.

How can I decided a language when taking in consideration its community, rather than the popularity? Any recommendations?

Is there any language community that show dedication and passion for developing, rather than learning a language to get a Job and a paycheck?
