mevans05, that link will be censored in about 10 seconds but what you describe is not a good situation - you're creating duplicate content before even the original version of the page has been indexed.

As for links being nofollowed on Twitter, Google can easily handle links from particular sites in a different way to the rest of the net and they already do this with Tweets. The nofollow is just a suggested directive anyway and may be ignored in certain situations on ANY site.
