TLDR
It is suggested that the in-degree of the tweet that initiates a reply tree may play an important role in forming the global shape of the reply tree.Abstract:
Structure of networks constructed from mentioning relationships between posts in online media may be valuable for understanding how information and opinions spread in these media We crawled Twitter to collect tweets and replies to construct a large number of so-called reply trees, each of which was rooted at a tweet and joined by replies Consistent with the previous literature, we found that the empirical trees were characterized by some long path-like reply trees, large star-like trees, and long irregular trees, although their frequencies were not high We tested several branching process models to explain the empirical frequency of these types of reply trees as well as more basic quantities such as the distributions of the size and depth of the reply tree Based on our modeling results, we suggest that the in-degree of the tweet that initiates a reply tree (ie, the number of times that the tweet is directly mentioned by other reply posts) may play an important role in forming the global shape of the reply treeread more

What is Twitter, a social network or a news media?
TL;DR: In this paper, the authors have crawled the entire Twittersphere and found a non-power-law follower distribution, a short effective diameter, and low reciprocity, which all mark a deviation from known characteristics of human social networks.

Twitter mood predicts the stock market.
TL;DR: This work investigates whether measurements of collective mood states derived from large-scale Twitter feeds are correlated to the value of the Dow Jones Industrial Average (DJIA) over time and indicates that the accuracy of DJIA predictions can be significantly improved by the inclusion of specific public mood dimensions but not others.

Measuring User Influence in Twitter: The Million Follower Fallacy
TL;DR: An in-depth comparison of three measures of influence, using a large amount of data collected from Twitter, is presented, suggesting that topological measures such as indegree alone reveals very little about the influence of a user.
