At first I was stumped about how to RSS-enable my blog for Safari. After doing a little bit of research at Apple.com, the fix is pretty simple. All you have to do is add a "<link>" tag to your HTML header, like below.

<link rel="alternate" type="application/rss+xml" title="RSS" href="feed://www.khan.org/blog/?flav=rss" />

Substitute your own URL for the href (again, if you're using Blosxom, appending ?flav=rss to your URL will suffice), and you're set.
