I have a suspicion - with just a few data points - that linking out to other related sites HELPS your ranking on Google these days. There's something going on down in the corners of the algo.
I recently bujilt a site for a friend and we included a minimum of two outbound links on every informational page. Her traffic and rankings are rather amazing for a site with rather modest intentions.
