Clean Links is a universal iOS app that takes dirty links (referral tokens, redirections, etc.) and spits back a nice, sanitized version.
One of my biggest pet peeves is sending
feedproxy.google.com links to Pinboard. Not only may the link break soon (knowing Google), it just looks hideous. With
x-callback-url support, you can automate the whole link sanitation workflow using an app like Launch Center Pro.
