Lisp in the real world


I have experimented with Lisp (actually Scheme) and found it to be a very beautiful language that I am interested in learning more about. However, it appears that Lisp is never used in serious projects, and I haven't seen it listed as a desired skill on any job posting. I am interested in hearing from anyone who has used Lisp or seen it used in the "real world", or who knows whether it is considered a purely academic language.

Please don't assume Lisp is only useful for Animation and Graphics, AI, Bioinformatics, B2B and E-Commerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list. — Kent Pitman
