<p>I've been seeing so much recently about functional programming and Clojure looks particularly interesting. While I 'understand' the basic description of what it is, I can't figure out how I would use it on a day to day basis as a web developer, if I can at all. A lot of what I have read focuses on the maths side of functional programming rather then typical programming situations found in regular OO. </p>

<p>Have I got the wrong end of the stick? Is functional programming totally un-related to web development? If not, are there any examples of it being used 'for the web'?</p>

A few examples off the top of my head:
Yahoo! Store is powered by Lisp (originally named
Viaweb
prior to acquisition)
Reddit
was fully prototyped in Lisp, although they
switched to Python
in 2005
Hacker News
is written entirely in Arc (a Lisp dialect)
