Here is a pdf of the facsimile issued by the US government's subpoena against Wikileaks in Twitter. You can find the full text of the news here. What does it entail?
Under Section 2. B, it seems that wikileaks' followers are also targets of this subpoena. As it states in sub-section 1, "records of user activity for any connections made to and from the Account, including the date, time, length, and method of connections, data transfer volume, user name and source and destination Internet Protocol address(es)".
There are roughly 637,000 wikileaks followers, and this should somehow serve as a warning to all of them. I don't think "unfollowing" now will do any good. One can always just visit wikileaks, get the same information, and not get subpoenaed at the same time.
