We've recently had our website tweeted by a couple of bigish media outlets 0.5m+ followers, some of the links are our direct url, and some are t.co urls.
From an seo point of view a link on their site would have been preferable, but i was wandering if even though the links are nofollowed, does google give weight to links from twitter accounts with high social clout, as i know they have fire hose access to the twitter api ?
