Questions sorted by votes: https://softwareengineering.stackexchange.com/questions?sort=votes
I'm not spending much time here, so maybe I'm missing something. But looking at the top questions - the best adjective I can come up with to describe them in my poor English is - "populistic". I guess the only reason they get so many upvotes is because everyone understands them. Otherwise I feel that there is not much difference between questions that get lot's of upvotes and those that are downvoted and closed immediately. It's a random process for me. (I have a theory though that it's partially a crowd psychology effect - the initial voting determines whether the question will be going seriously up or seriously down.)
The questions/answers that require some research effort and expertise aren't upvoted that much, perhaps for the very reason that very few can understand/answer them.
EDIT: Looking at those top-voted questions one gets confused about what questions are welcomed here. I know that I was and still am.
