yes, but it is trivially easy to set the archive up so only those users who want their email addresses obscured will have that happen. it does not make sense to me that you want to force those people to stay visible because you may benefit from asking them something... to thwart you, they could just subscribe from two addresses, post from one (which address gets recorded in the archive) and send all email to that address to /dev/null.
i do not care about having my address obscured, nor do i understand the long history that has led to such a contentious debate on this matter. my left-leaning impulses tell me that anything that enhances the choices of the list members is a good thing. of course, it is unfair to expect doug or marco to labour to please each whim and fancy, but peeling away all the angry words, a decent case has been made for obscuring addresses (including an example of an actual listmember losing a job as a result of posts made to this list), and doug and marco seem willing to implement the changes.
