I agree with you about retarded questions and difficult to track answers. I think reddit style comments is a better solution than getting rid of the livespills though. See the above, or this for examples. http://www.reddit.com/r/IAmA/comments/9oygt/i_gained_35_lbs_of_lean_muscle_mass_in_the_past/
I haven't read either of these links, so I can't comment on how interesting they are, but they do show how a different format can make discussions easier to follow. And the best comment threads (as upvoted by the community) will be the ones at the top.
