For a long time I've had Delicious setup to post my Delicious bookmarked links to my blog. A few weeks ago something started introducing "\n"'s into my posts.
You can see what it's doing on this post: http://blog.mattgoyer.com/archives/2009/06/06/links-for-2009-06-06/
I'm not aware of any changes to my setup. Also, the Delicious support team doesn't believe the problem is on their end.
Thanks,
Matt
