DrWhoNews was far and away the most active Tweeter on 1st November 2009. The Twitter profile for this user terribly helpfully shows the username as DrWhoNews and their location as Gallifrey (Doctor Who's fictional extraterrestrial home planet). Although DrWhoNews has Tweeted far too often for their date of joining to be found - with over 11,000 Tweets published to date - the Twitter account follows over 4000 Twitterers and has a whopping 3875 people following it giving Drwhonews significant visibility/potential viral impact on Twitter.
Although links spin out in almost every update from DrWhoNews, and although there are many many updates each day, this does seem to be a personally maintained news stream - either from individual manual additions or aggregated feeds of Doctor Who and Torchwood news. The stream has posted links to a blog (http://drwhonews.blogspot.com/) and to fan fiction on LiveJournal but does not explicitly specify a related website other than the Twitter Stream. A Google search (which I felt ethically justifiable for this less personal Twitter user) for the phrase "Doctor Who News" reveals a website which may be the source of Tweets, The Doctor Who News Site.
DrWhoNews has only a single connection to the other #Torchwood twitterers observed here, the account follows the @torchwoodforum user.
