Facebook lets you import existing blogs into your "notes". I had no problems with my old blog (not on wordpress), but have just set up a wordpress blog. I went to make the change at Facebook - it asks for the feed, so I entered http://blog.wordpress.com/feed/ (yes, I substituted "blog" with my username). But I get the following error - "Import Failed We couldn't find a feed using the URL you provided."
Any help?
