Depends on where the time is saved. If it's in figuring out how to do something in Django where StackOverflow is flooded with outdated answers, sure. I see those kinds of savings. But the tragic beauty of programming is that a little time saved today can very well mean lots of time lost later. The former you can measure, the latter is a tougher nut.
