I just discovered that when I use the "save elsewhere" feature on a bookmark with an ampersand in the URL, the exported URL breaks at the ampersand character. The ampersand and everything following it is dropped. I can't believe i never noticed this till now -- it means a bunch of my delicious bookmarks point to the wrong page.
For example, when I bookmarked the URL
http://www.sciam.com/article.cfm?id=how-loss-of-privacy-may-mean-loss-of-security&print=true
the following URL was sent to Ma.gnolia and Delicious:
http://www.sciam.com/article.cfm?id=how-loss-of-privacy-may-mean-loss-of-security
