Hey all, I told my student to check out the discussion here, and he just wrote me back this: "Thank you very much. I love the discussion on hubski. Some people focused on the truth value of the statement like I did too. However, I think I get the point now. Even if this can be true in 99.99% of the cases, it still isn't a good practice to not leave any room for exception, especially that this is still debatable. It is more about not sounding "arrogant" and absolute rather than whether or not it is true or not. I think hearing from all of you, theadvancedapes, thenewgreen, kurmit, b_b, MattholomewCup, littlebirdie, and BLOB_CASTLE made a difference to him rather than just trusting me. I don't know if hubski has ever been used as a teacher's aid before but this process and the outcome just fascinated me!!!
