It seems to me that the new IT Security site and Serverfault are very thinly sliced and might create confusion in its shared users about what kind of questions go where. For example, the question "How do I secure my $OS webserver?" is clearly a question about security, but it is also a question and a topic which systems administrators are likely to ask about and likely to have experience with - and thus belongs on both the IT Security site and on Serverfault.
Is there a way to more clearly clarify which questions should go where? Do you think that the two sites should be merged together, and/or one absorb the other?
