Theological insights have been developing for 2000 years - and the reason is not because God is saying anything new. Rather, our collective experience of God is new each and every day. As a result, the application of what God said to our present circumstances and outlook will always be refreshed.
That said, our outlooks do change at a slower pace than your average coding language or piece of software. We will never reach the volume of new stuff that SO has, but as long as people are growing, there will always be new applications.
The trick, of course, is that the most immediate applications - pastoral advice - is off-topic. Still, there are meta issues within doctrine that will always relate to present experience.
In Islam.SE, they worry about actual implementation of practice a lot. As such, they will always have edge case questions. And, while no disrespect to Islam.SE, I think we actually have the far more interesting site, because we don't care about application. In a sense, Islam.SE is very much at the 'give me the codez' level. http://islam.stackexchange.com/questions/7749/what-should-i-do-if-my-cell-phone-rings-during-salaathttps://islam.stackexchange.com/questions/7749/what-should-i-do-if-my-cell-phone-rings-during-salaat is an interesting adaption of culture to practice.
Christianity.SE, however, is far more like Computer Science than programming. The vast majority of us are not rules based, but rather doctrine based. (I'll save the orthopractic vs. orthodoxic debate). As such, we are not likely to be as interested in the implementation details. But we are still confronted with the issues, if not the practice. I doubt anyone would ask "What should I do if my cell phone goes off in the middle of the sermon?" (Answer: Silently leave the building and never return :0) but it is relevant to ask "How does the attention sapping culture affect a Christian's ability to meditate on the goodness of God?"
These questions are harder to ask, but they are still there.
