RSS Feeds in Facebook, Walled Garden of Fail
If you hook your RSS feed up with Facebook, the items keep you inside the walled-garden of Facebook fail.
Let me give you an example.. so if I see this RSS item show up in the facebook stream:

I click on the link and it sends me to a Facebook note.

The RSS feed links should go to the intended context, my blog! #facebook #walledgarden #fail

Especially with our own blogs, on our own sites, we're likely to want to keep our visitors here.
I'd say to give all your Facebook readers instructions on how to get a feed-reader. It's one of those things most people should have. In years past, I'd almost been using my email as a feed (getting notifications from every site when something happened).
Facebook reads your feeds, and posts new notes (create duplicates of the data on facebook's servers).
It's basically an auto-blogging utility allowing you to clone your existing blog on facebook. It is not intended to provide an RSS feed of your blog to your facebook friends, directing them to your blog.
Why don't you use a facebook application like RSS Graffiti that publishes your feed on your wall and links directly to your site?
