Stack Overflow doesn't really support questions that do not have a specific answer, such as "What are the features you would want in a programming language that are lacked by most programming languages?". Is there a Stack Exchange site or other external site specifically made for this?
The "What are the features you would want in a programming language that are lacked by most programming languages?" question isn't really suitable for Stack Exchange, it's a poll for opinions rather than a question on an actual practical problem. It's not a bad question, it just doesn't work with the Q&A format of Stack Exchange, as there is no sensible way of vetting answers.
We welcome some subjective questions on Programmers Stack Exchange, however your question would most likely be closed as "not constructive".
So I finally decided the only person that really answered my question was @Pekka in a comment:
Objective, answerable questions are at the core of SO's concept. Would you walk into a factory that has been building cars successfully for fifty years and tell them that they need to start building trucks because trucks are useful? There are many other places (like Quora) that work more in the way you desire; do check them out. Web sites are not real life; the are virtual communities of people with different dynamics
And to add to his answer, one of my friend told me he asks such questions on a typical forum/message board. So I guess I'll be going for that option. Thanks to everyone who really tried to help.
