Emacs is used by many lispers but not all of them.The most famous non Emacs lisper is Paul Graham. I don't mind using Emacs and Slime on Linux but for a visual type of person they suck compared to modern IDE's. I rely a lot on visual clues and speedbar is a poor man alternative. Franz and Lispworks are making good ides and many commercial organizations are buying and using them. The implementations you mentioned are all open source and don't have resources to develop proper IDE since there is no big company to back them up, such as IBM financing eclipse. So they choose proper course of action of improving their implementations with Emacs + SLIME as their programming environment.

First thanks to everybody for reading my posts. Currently I'm using regularly common lisp, java, c#,c/c++ and SQL. I bought Programming Clojure & Practical Clojure and went through them. I would have bought both Clojure in action and Joy of Clojure (written by starter of this thread fogus) if Manning accepted credit card payment from Macedonia. I'm little tired of everything Java related, that includes Clojure, so I'm using my spare time to learn OpenCL. Regarding Haskell. I haven't programmed in it since I wrote the post farewell haskell. The reason for that is my programming style for which Haskell is ill suited which described in the farewell haskell post in the paragraph starting with: It may interest you to know that most of my development .. http://tourdelisp.blogspot.com/2008/03/farewell-haskell.html I don't hate Haskell but its not in list my favorite language either() though as one favoring functional style I cheer news like this http://bit.ly/djs4J5. Also I prefer to say what I'm thinking and be rude if necessary then hide my message between being politically correct watered down politician talk. On the other hand I have high opinion about SPJ and enjoy his talks http://bit.ly/4BG5Dp and many of his papers. In the end language wars are pointless, use the language that suits yourself and have a marry hacking.
() For those interested my favorite languages are lisp dialects (cl,scheme and clojure), array languages (j & q), Prolog, Erlang and concatenative languages (Factor, Cat & Joy)
