Even so, blaming Joe Average for not having the correct settings in Tweetdeck when he's retweeting is hardly a viable way to fix it. New users expect software to do the right thing, which it obviously isn't in this case.

Besides, the functionality is useful for normal length links, I'm just saying Tweetdeck should realize that when saving one or two characters, or even making a link longer by "shortening" it, or if said url is already shortened, the program isn't being very smart when not skipping the shortening in that case.
