What??... :o
I think this is very much a wrong perception! Sure, there has been a lot 
of articles, publicity and buzz surrounding duck typing in the past few 
years, but that doesn't meant it's "all the rage". More concretely, it 
doesn't mean that duck typing is popular, either now, or heading that 
way in the future. I think dynamic languages are somewhat of a niche 
(even if a growing one), but not really heading to be mainstream in 
medium/large scale projects.
Rather I think that the duck typing fanboys are just very vocal about 
it. (Kinda like the Tea Party movement... )



BTW, just as a clarifying side note, duck typing is nothing new in terms 
of language features. Duck typing is just dynamic typing as combined 
with Object Oriented. What is new about duck typing is not so much in 
the language, but rather the development philosophy that states:
  * dynamic typing with OO is an equally valid approach (if not better) 
than traditional static typing OO, for thinking about objects and their 
behavior,
  * documentation, clear code, and testing are good enough to ensure 
correct usage (especially testing, in some circles).

Note: I'm not implying I agree with the above, I'm just paraphrasing.
