Ha, you are right, I forgot PHP. However I think PHP is really a language where people agree that it has lots of weird corner cases.<p>So its popularity is really historical incident, in particular I think, that it was the first hack (see worse is better) to allow to easily deploy dynamic web applications (via web-server side interpretation of code, which got popular in Apache). Furthermore PHP hosting is still very popular in low-cost bundles to integrate e.g. Wordpress.<p>Clojure is another nice language, but could benefit from typing. :p Maybe the main &quot;problem&quot; for dynamic languages ist the fact that it requires more discipline on the Programmer&#x27;s side, so I imagine it is popular for smaller teams, but this is hard to achieve for bigger development efforts, where you can benefit from a stronger type system.
