This question already has an answer here:
I have been noticing over the last month (on Stack Overflow), that simpler (perhaps somewhat duplicate) questions seem to get a lot of attention, as compared to the more challenging long-ish questions.
As a result, the answers tend to receive a greater number of upvotes (simply due to greater views) even though the answer might be a copy of an already existing Q/A. Moderators do take care to mark most of these questions as [duplicate], but many slip through. What could be a possible solution to this?
