Fashion. Demand for technology is usually driven more by copying what everyone else does than by merit. Consider: Fred is a busy manager who has to start a new website and is dissatisfied with the technology he's previously been using. Does he have time to learn Ruby on Rails, Django, CherryPy, Drupal, and thirty other web technologies, to systematically and objectively decide on the best language for the website? Of course not. Even evaluating *two* technologies is probably beyond his time or budget constraints. So he does a search on the Internet, or reads trade magazines, or asks his peers, to find out what everyone else is doing, then copies them. "Oh, they're using Ruby on Rails, it must be good." So now he decides to use Ruby on Rails, advertises for RoR developers, and the cycle continues. But is RoR actually better for his specific situation? Doubtful. Presumably RoR is better for *some* specific jobs. At some point, early in RoR's history, it must have been a *good* solution. But unlikely to be the *best* solution, just better than whatever people were using before. And so RoR will be the easy choice, not the best choice, until such time as RoR is no longer satisfying developers. And then there will be a sudden, and random, phase-change to some other tool, which will become the next easy choice. > 3.

But then, what do I know, I'm just as much a follow of fashion as the next guy. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
