Nick,
Maybe I am missing the bigger picture, but why are you redistributing your content when folks can easily pick it up with search engines, or your comments in other people's blogs (linked back to your own)? Plus, providing a feed will encourage subscriptions, and in turn contribute to viral marketing. Enable multiple 'reads', i.e., on the site, in a feed, or via email.
I followed the link in your Post here, and looked at the blog 'entries'. The one I looked at ("An introduction to link building") said "Comments are closed". Encouraging comments is one way to boost traffic, links, and rankings.
Like I said, maybe I am missing something here.
