This site (M.SE) has increasingly become a spot for students to post their homework solutions and get an answer to their question with no additional effort by the OP. Because of the willingness of students to post blatant homework questions (which is to be expected), and the irresponsible eagerness by most users to answer such questions unashamedly for reputation points, I can no longer contribute to the site. It's been fun while it lasted, and after while I may even feel the need to revisit the site. Until then.
