Technologists are better at understanding technology than business. If you are playing around with technology on your own dime, use the best tool for the job. If you are writing code professionally for a company, consider all the long term needs of the company. If you bring in a new language/framework/platform, they will have to staff for that. The default behavior should be to pick one of the most prolific technologies on the market and use that until it's no longer feasible.
