I know there are refs on alegro and other links on the web which point out lisp based applications. I also have come across where pointers point out to viaweb being developed in lisp and that being migrated away from lisp. Similarly reddit development starting with lisp and then moving off to python etc. Why doesnt lisp perform as web application programming language though it has a whole bunch of programming features better than other languages?
I also have tried my hands on a mix of some of the lisp based libs/frameworks (hunchentoot, weblocks, cl-who, clsql, postmodern and others) which help to develop web apps in the proces of figuring a stable mix of lisp based components to develop the web app.
Please share your experiences with web app development with lisp which are running in production environment currently and not those just being replaced or migrated to someother language (eg viaweb which should be now 10 years old, or reddit even).
