New Data on Twitter

„We analyzed data through the end of 2009. Where the data overlapped with our previous analysis (which ran through August 2009), the findings were highly consistent. However, the updated data revealed the following noteworthy trends:

  • Twitter ended 2009 with just over 75 million user accounts.
  • The monthly rate of new user accounts peaked in July 2009 and is currently around 6.2 million new accounts per month (or 2-3 per second). This is about 20% below July’s peak rate.
  • A large percentage of Twitter accounts are inactive, with about 25% of accounts having no followers and about 40% of accounts having never sent a single Tweet.
  • About 80% of all Twitter users have tweeted fewer than ten times.
  • Only about 17% of registered Twitter accounts sent a Tweet in December 2009, an all-time-low.
  • Despite these facts, Twitter users are becoming more engaged over time when we control for sample age.“

Who Owns The Data?

„A further point must be noted with regard to data, and that is user concerns about privacy and their rights to their own data. In many of the early web applications, copyright is only loosely enforced. For example, Amazon lays claim to any reviews submitted to the site, but in the absence of enforcement, people may repost the same review elsewhere. However, as companies begin to realize that control over data may be their chief source of competitive advantage, we may see heightened attempts at control.

Much as the rise of proprietary software led to the Free Software movement, we expect the rise of proprietary databases to result in a Free Data movement within the next decade. One can see early signs of this countervailing trend in open data projects such as Wikipedia, the Creative Commons, and in software projects like Greasemonkey, which allow users to take control of how data is displayed on their computer.“
