I think they are talking about section B of attachment A (http://www.salon.com/news/opinion/glenn_greenwald/2011/01/07/twitter/subpoena.pdf http://www.salon.com/news/opinion/glenn_greenwald/2011/01/07...) : "B. All records and other information relating to the account(s) and time period in Part A, including: 1. Records of user activity for any connections made to or 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);" I guess it depends on how they are defining connection. Connection could mean a user following that account, replying or direct messaging. On the other hand they might just want details on each time the user named in the subpoena logged into their account. I am guessing that this isn't a request for 637,000 users information because Twitter has notified those accounts where information has been requested and they certainly have not notified 637,000 people.
