Ideally responses should be *interleaved* between parts of the quoted 
message, rather than just dumped at the end. The idea is that it's a 
conversation:

    Fred said:
    -> How do I exfoliate my monkey?

    Get a friend to hold it down while you rub it all over 
    with Extra Strength Monkey Exfoliating Cream. When you 
    are done, give it a banana as a reward.

    -> Once I have my exfoliated monkey, how do I convince
    -> others that it is my child?

    Dress it in children's clothes, and make sure you tell 
    people that he or she has a very sensitive artistic 
    personality, and that is why you allow it to climb the
    walls.


sort of thing. This also gives the writer the opportunity to trim out 
parts of the irrelevant text which is no longer relevant to the 
conversation, although it is considered polite to give some indication, 
usually [snip] or [...], that you have done so.
