Every Stack Overflow user has encountered a question with many thousands of upvotes that could have been answered by a brief look at a man page (several git questions fall into this class).
While I don't mean to suggest that such questions aren't useful, I do wonder if there are some users who "land rush" new topics, asking very basic questions about new technologies with the hope of accruing massive reputation. Of course, distinguishing between a "sincere" question and one that is posted merely to accrue reputation is probably tricky (although looking at users who have many such questions in widely disparate topics would be a clue).
Do the Stack Overflow managers look for this? Do they even care? Should anyone care?
(Note: it bothers me but perhaps I am in the minority.)
