Recent changes have been made to YouTube. They make it unable for you to see the link when it's done uploading. You can still get the link to the video before it is done processing completely, but until then, no one will be able to see it.
To get it, go to the "My Videos" link at the top. It should be up at the top but still uploading. Click on the Edit my Video button and in the embedded HTML section, you should see a link written twice in that mumbo-jumbo stuff. Copy it, and it will be yours to paste whereever you wish.

Go ahead and try it. Remember, due to these new changes, it could take up to a full day before anyone is allowed to see it.
