Just saw a CNN google-powered search in my logs where the Title of the page had a link with an embedded space, similar to the way google adds spaces to their urls. Therefore clicking the "title link" doesn't work, but funnily enough there is no space in the url link and clicking the "url link" works.
Doesn't mean much to me personally but some of you google watchers out there may find it interesting. Sorry, can't give you the real example (no stickies please). But hopefully someone will be able to duplicate the behavior.
