The day coders pick Java/C#/Cobol because that's where the jobs are. Companies might have chosen them for sound technical reasons (or not), but day coders won't learn languages/tools that don't pay the bills. For reference, a Monster search for .net jobs in Chicago gives 266 results. Java gives 403. Lisp gives 22 for the entire country. Not something to learn if you just want a job to fund your real life.
