Thanks. Much better explanations than my feeble attempts.
Thanks, John! How about extending this "imaginary FReeper" concept to actually allowing someone from each bump_list to create a profile page, like you do for the semi-imaginary (!) Sidebar Moderator, where they could archive classic OLDER threads of importance to that "Special Interest Group" - since clicking on the bump_list itself will only recover threads less than about thirty days old?
