Answer: Excessive flexibility hurt ALGOL60 since languages that are difficult to learn were not as well received as languages with a more rigid structure. Then the most important reason that ALGOL60 was not very widely used was because of a lack of support from IBM, who was at the time the preeminent company for using computer languages. Without some help from a large corporation, ALGOL60 did not have much of a chance, much like COBOL without the DoD.
