Twitter and Politics
The 2009 German General Election started with the impression of Obama’s online campaign fresh in mind
Due to several high-profile incidents, German media and politics focussed on Twitter at least as much as on other social networks
Twitter Overview»Micro-publishing« — publish short messages
Re-Tweet — quote message including attribution
Directed (@-)message — explicitly sent to a recipient
Topic tags (#) — defines the topic of the message
High degree of mobile usage (~15% in our dataset)
3
Data CollectionBootstrap: List of political twitter users(Assembled from several websites compiling lists of politicians on twitter)
Growth: perpetual search for #tags(Add new users to sample)
Capture: Collect all new tweets(Also crawling archives for coverage over entire time range)
Graphs: Nightly snapshot of friend/followers

Dataset
Three months prior to General Election
A sample of Germany’s politically active twitter users — 33 048 individuals
A complete archive of their communication (public tweets) — 10 109 894 messages
A temporal map of their connections

Defining Links
Followers are a questionable indicator of influence (Cha et al: “The Million Follower Fallacy”)
Intentional, meaningful interaction as a link: @-messages and quotes (re-tweets)

Follower gain over sample timespan correlates with intensity of interaction(Spearman’s Rho rs = .54, two-tailed p ≃ 0)
Corresponds to “preferential attachement” theory on network growthNew participants attach (follow) to most visible nodes

Results
Reach on twitter is very dependent on a small group of users (new gatekeepers)
Preferential attachement makes entry into twitter ecosystem difficult
Politicians are only successful if they attach to existing topics/trends/conventions? (e.g. Jörg Tauss, Piratenpartei)

Results II
Dedicated “political” communities do not play a significant role.
Dedicated “political” users do (mostly) not play a significant role.
Political communication happens ad-hoc in issue-driven topics among non-political tweets and topics.

Translated:“I’ll be glad once the election campaigns are over and we can all like each other again. Especially once the dull discussions come to an end.”
