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

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 once someone follows them on [...]

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 [...]

Map of connections between Web 2.0 companies and investors

Here are two new maps I created with Pajek (which unfortunately cannot display graphics as nodes) using the Crunchbase API. This time they are about the connections between a number of Web 2.0 startups by their common investors and between these investors.
If, for example, the same financial organization or person is investing both in Twitter [...]

Who’s investing in microblogging and lifestreaming?

Want to know which venture capitalist invested in which web 2.0-company? Take a look at Crunchbase. It’s all there. And the best thing is: it has a beautiful and responsive API. I couldn’t resist downloading a few entries from this database to visualize the network of investors and companies that’s evolving around the new microblogging [...]

Friendfeed’s network magic

The crucial difference between old mass media and new social media lies in the network magic, services like Friendfeed are able to perform.
One thing should immediately be evident if you’re using the FFSixDegree tool I coded yesterday: the real power of Friendfeed as a communication infrastructure is its network effect. Even if you are subscribed [...]

FFSixDegrees - take a closer look at your Friendfeed network

Just finished (for the moment) a small application that can be used for social network analysis of Friendfeed data. See for example this visualization of my Friendfeed contact network.

The application loads your contacts and your contacts’ contacts from Friendfeed and not only displays your number of friends and friends-of-friends but also the five most influential [...]

My social network on Friendfeed

How does my second order social network on Friendfeed look like? A network analytical exploration.
As the six degrees of separation experiment by Stanley Milgram went through press and social media again, I thought it would be nice to visualize my Friendfeed connections. I wrote a quick php hack that downloaded all my connections and my [...]
