Curating Flipboard content: two varieties of personalization

The killer app A few weeks ago, Flipboard (often referenced to as the iPad killer app”) was finally launched for the iPhone. And what the developers did to transport the flowing way of navigating your streams and news sources to the much smaller screen of the iPhone is more than convincing. Flipboard has very quickly […]

Almost 5000 tweets per minute during Obama’s inauguration

It is no big surprise that Obama’s inauguration generated a lot of buzz on Twitter. The hashtag #inaug09 quickly became one of the most frequently typed Twitter tag. But exactly how often did people tweet about Obama’s inauguration? We have quite detailed data about this day on Facebook: Since this morning more than 1.5 million […]

TwitterFriends: Overlapping networks

One of the new features of TwitterFriends is a visualization of your incoming and outgoing networks. Remember: Your incoming network includes all Twitter users that replied or referred to you on Twitter the last 30 days at least twice. And the outgoing network – your relevant net – includes all Twitter users you referred or […]

How efficient is your Twitter network?

Valdis Krebs just wrote a great blog post about his strategy of maximizing his Twitter network efficiency. We all know, the more people you are following on Twitter, the more difficult it gets to keep in touch with all of them. Most often you are reducing your network size by selectively reading about and replying […]

Visualizing Twitter networks

Now, I’ve finally rolled out the network visualization mode for TwitterFriends. It does not show the entire network of Twitter contacts (followees and followers) because it would simply be too large and confusing. Also, it would be not very meaningful, since contacts are easier added than removed. Therefore, only the “relevant network” of contacts, a […]

Measuring relevant networks

See our friends, see the sights, feel alright (Supergrass) Relevant net I’ve already mentioned the paper by┬áBernardo A. Huberman, Daniel M. Romero and Fang Wu about Twitter’s social networks (pdf). The point that interested me most was the distinction between contacts and friends. Especially for people with a liberal following policy (i.e. that follow back […]

Networks that matter on Twitter: the @-Crowd

Finally I found a research paper that analyzes Twitter from a network analytical perspective. The main message of the paper “Social networks that matter: Twitter under the microscope” by Huberman, Romero and Wu (see also Jeremiah Owyang’s summary) is: the number of people you follow on Twitter is not the whole truth. It’s more interesting […]

Towards a global database of social media marketing case studies

Which companies are using social media like blogs, social communities, internet forums or video/picture sharing for their marketing efforts? The first lists of case studies are being published right now on various blogs: Peter Kim has a long list with over 300 brands’ social media efforts. Then there are many case studies if you take […]

What is Social Media? A not so critical review of concepts and definitions

In 1952 Alfred Kroeber and Clyde Kluckhohn published their seminal work “Culture: A Critical Review of Concepts and Definitions”. They provided a systematic overview of 164 definitions of this anthropological key concept. I did not find as much definitions of social media and furthermore the differences between definitions social media are far smaller than the […]

Obama and the global web

Global web? Sounds like redundancy, but in fact many phenomena on the world wide web aren’t so global at all. Although non-western languages are of rising importance online, English still is the most spoken language on the web. And so it should be clear that Barack Obama’s election is mostly an American or perhaps Western […]
