Network scientists have discovered how social networks can create the illusion that something is common when it is actually rare. One of the curious things about social networks is the way that some messages, pictures, or ideas can spread like wildfire while others that seem just as catchy or interesting barely register at all.

"The effect is largest in the political blogs network, where as many as 60%-70% of nodes will have a majority active neighbours, even when only 20% of the nodes are active." How convenient :-)

Sounds too super to be true, no?

> Sounds too super to be true, no? Yeah, how else may it sound, being a combination of hi-quality (I assume) research targeted at attracting funding, raised to the power of Science Daily's pop-pseudo-scientific journalists' bu****it? Original article starts with a cool sentence too: > The ultimate proof of our understanding of natural or technological systems is reflected in our ability to control them. ...a good starting point for a never-ending philosophers' debate... Now seriously, because of a big name behind the study, I'm very curious to read the original article. Although I expect the conclusion to be that in practical cases (i.e. the cases of "networks" you *would like to* "control"), you need to control all nodes or something equally impractical...

then I am looking forward to reading your conclusions here after you will have actually read the paper

"The Complexity of Nash Equilibria,", It also suggests that the Nash equilibrium may not be an accurate prediction of behavior in all situations. Daskalakis's research emphasizes the need for new, computationally meaningful methods for modeling strategic behavior in complex systems such as those encountered in financial markets, online systems, and social networks.

it seems that there are indications that we are differently wired .... Sex differences in human behavior show adaptive complementarity: Males have better motor and spatial abilities, whereas females have superior memory and social cognition skills. Studies also show sex differences in human brains but do not explain this complementarity. In this work, we modeled the structural connectome using diffusion tensor imaging in a sample of 949 youths (aged 8-22 y, 428 males and 521 females) and discovered unique sex differences in brain connectivity during the course of development. Connection-wise statistical analysis, as well as analysis of regional and global network measures, presented a comprehensive description of network characteristics. In all supratentorial regions, males had greater within-hemispheric connectivity, as well as enhanced modularity and transitivity, whereas between-hemispheric connectivity and cross-module participation predominated in females. However, this effect was reversed in the cerebellar connections. Analysis of these changes developmentally demonstrated differences in trajectory between males and females mainly in adolescence and in adulthood. Overall, the results suggest that male brains are structured to facilitate connectivity between perception and coordinated action, whereas female brains are designed to facilitate communication between analytical and intuitive processing modes.

I like this abstract: sex, sex, sex, sex, SEX, SEX, SEX, SEX...!!! I wonder if the "sex differences" are related to gender-specific differences...

for Tobi! nice analogy between the threat and the fast responding in human network

Yet another example of "because scientifically accurate title would sound sooo boring".

not the most fancy social network - but one around an interesting topic for us ...

Blogosphere as social network (check the image!)

p2p is still massive and seems to be constant, but real-time entertainment is taking over. More details here: http://www.sandvine.com/downloads/documents/05-17-2011_phenomena/Sandvine%20Global%20Internet%20Phenomena%20Report.pdf

how reliable is this ... looks strange that e.g. secure tunneling and social networking are diminuing, isn't it?

Centralise all your networks / messaging in one place. One of the best I've seen available. Havent tested yet... (KdG)

nice new social network - by French! ... also nice layout :-)

but so far only an announcement ... they want to be ready in autumn only ... :-(

yes, but already 172000 dollars of donation (!!) and plenty of guys offered their service for the coding ! this is something a lot of people is waiting for !

Anything that can has a chance to save us from the Facebook abomination is welcome...

If you're looking for interesting articles or sites devoted to Kobe Bryant, you search Google. If you're looking for interesting comments from your extended social network about the three-pointer Kobe just made 30 seconds ago, you go to Twitter.

Social networking in companies (german only)

be happy and infect your neighbors with it :-) ....

"Yammer is a tool for making companies and organizations more productive through the exchange of short frequent answers to one simple question: What are you working on?" Have you tried it yet?

hard to choose ....

Facebook for scientists

can we use this for our planned network and also host it on our server?? (LS)
