progamming language book sales

interesting analysis of book sales by programming language. in a nutshell scripting languages are spiking up in popularity. given that most of the scripting languages encourages functional style (list comprehensions, map, apply) of programming this bodes well for encouraging people to look at more robust (type enforcement), functional languages (F#, boo, nemerle, scala, ocaml, haskell). gut feeling is that functional and domain specific languages are gaining momentum. may be eventually DSL's will replace the multitude of framework API's. http://radar.oreilly.com/archives/2007/05/state_of_the_co_10.html
