It's official, Yahoo now also obfuscates search result links with gibberish the same way Google does, but misleadingly shows you the original URL in the browser's status bar. If you do a search for a site then right-click to copy the source URL, instead of getting the actual search result, you get a string of random characters, no doubt practical for their uses but extremely irritating for us.
For example, doing a search for Grilled Cheese Sandwich will show a Wikipedia page as the first result with the correct URL:

Fortunately it's easy to strip out most of the junk given the URL you actually searced for is merely appended to the end, but it's still a waste of time. Google and Yahoo really, really, REALLY need to stop doing this!
