Simple.
Just be logged in linkedin.com and twitter.com where you already have activated the sharing options between the two Web sites. So.
Have a try: include the “twitter.com” url in a tweet, without any “@” and even “#” that makes tweets unreadable and you may have a NOT FOUND from twitter in the shared link. Again. Billions dollars valued Web sites and they still so buggy all around after years of development. We just talk about simple links exchange and the shorter links system is just increasing bandwidth traffic and could even let you down on a not found or server not found. Bandwith eater and no guarantee on server response. Shortering links are useless and buggy. Ridiculous and counterproductive.
Here the test on Firefox 3.6.17 on Mac OS 10.6.7.
