"The future masters of technology will have to be lighthearted and intelligent. The machine easily masters the grim and the dumb." -- Marshall McLuhan, 1969

On the Bursty Evolution of Blogspace
Topic: Blogging 1:59 pm EDT, May 24, 2003

We propose two new tools to address the evolution of hyperlinked corpora. First, we define time graphs to extend the traditional notion of an evolving directed graph, capturing link creation as a point phenomenon in time. Second, we develop definitions and algorithms for time-dense community tracking, to crystallize the notion of community evolution.

We develop these tools in the context of Blogspace, the space of weblogs (or blogs). Our study involves approximately 750K links among 25K blogs. We create a time graph on these blogs by an automatic analysis of their internal time stamps. We then study the evolution of connected component structure and microscopic community structure in this time graph.

We show that Blogspace underwent a transition behavior around the end of 2001, and has been rapidly expanding over the past year, not just in metrics of scale, but also in metrics of community structure and connectedness. This expansion shows no sign of abating, although measures of connectedness must plateau within two years. By randomizing link destinations in Blogspace, but retaining sources and timestamps, we introduce a concept of randomized Blogspace. We observe similar evolution of a giant component, but no corresponding increase in community structure.

Having demonstrated the formation of micro-communities over time, we then turn to the ongoing activity within active communities. We extend recent work of Kleinberg to discover dense periods of "bursty" intra-community link creation.

This paper by Prabhakar Raghavan of Verity was presented this week at the International WWW conference.

Information Flow in Social Groups [PDF]
Topic: Technology 12:24 pm EDT, May 24, 2003

We present a study of information flow that takes into account the observation that an item relevant to one person is more likely to be of interest to individuals in the same social circle than those outside of it. This is due to the fact that the similarity of node attributes in social networks decreases as a function of the graph distance.

An epidemic model on a scale-free network with this property has a finite threshold, implying that the spread of information is limited.

We tested our predictions by measuring the spread of messages in an organization and also by numerical experiments that take into consideration the organizational distance among individuals.

This paper is sort of a follow-up to the Email as Spectroscopy paper. You can find a PowerPoint briefing on it at

Guardian Unlimited | 'Will I be deported?' Neil Young blasts Bush
Topic: Current Events 10:14 pm EDT, May 22, 2003

] It is difficult to find supportive things to say about
] George Bush unless your construction company is
] rebuilding Iraq, but it would be a droll irony if it was
] him we have to thank for Neil Young's latest creative
] renaissance.

New album coming out. He is bitching about Bush, FoxNews is already attacking him..

Relevant quotes:

"The US is like a baby with a bomb," ... "The reaction to France that the administration allowed to happen is so immature. These people have their own opinion - they're French! They're not fuckin' Americans, they're French ! Vive la difference, hello? And this big deal about Bush landing on an aircraft carrier? Talk about a six-year-old kid with a Tonka toy - we got it here." ... "I think the world today, at least the US and to some extent Britain now, is experiencing this kind of Big Brother thing," ... "It's not what we thought we were gonna be doing, a lot of the people's civil rights have been compromised, and we don't know what's going on. If I keep speaking my mind, will I be deported? I'm not very happy with the state of things. Music is being banned, and we have people in control of the radio stations who are the same people in control of the concert halls. They're also tied into the [US] administration and are sponsoring pro-war rallies. It's not good. It's interesting ." ... "The real point was, somebody asked the president what he thought and he said, 'It's America, it's a free country, they can have their opinion, but there's nothing we can do about it if nobody goes to their shows or plays their songs,'" "But he's so out of touch that his advisers haven't told him that their record sales spiked upwards when that happened, and while the airplay went down the sales went up and their concerts all sold out." ... "It's a robust time, probably the most fertile time for the underground and for revolution since Nixon. I'm not talking about political overthrow; I'm talking about just general cultural revolution. Bush has polarised the country and is creating this breeding ground for an opposition. In the next couple of months, they'll probably make it unpatriotic to be Democrat. It's pretty crazy."

William Gibson | Talk at Directors Guild, 05/17/2003
Topic: Media 6:11 am EDT, May 22, 2003

But I need to diverge here into another industry, one that’s already and even more fully feeling the historical impact of the digital: music. Prior to the technology of audio recording, there was relatively little one could do to make serious money with music. Musicians could perform for money, and the printing press had given rise to an industry in sheet music, but great fame, and wealth, tended to be a matter of patronage. The medium of the commercial audio recording changed that, and created industry predicated on an inherent technological monopoly of the means of production. Ordinary citizens could neither make nor manufacture audio recordings. That monopoly has now ended. Some futurists, looking at the individual musician’s role in the realm of the digital, have suggested that we are in fact heading for a new version of the previous situation, one in which patronage (likely corporate, and non-profit) will eventually become a musician’s only potential ticket to relative fame and wealth. The window, then, in which one could become the Beatles, occupy that sort of market position, is seen to have been technologically determined. And technologically finite. The means of production, reproduction and distribution of recorded music, are today entirely digital, and thus are in the hands of whoever might desire them. We get them for free, often without asking for them, as inbuilt peripherals. I bring music up, here, and the impact the digital is having on it, mainly as an example of the unpredictable nature of technologically driven change. It may well be that the digital will eventually negate the underlying business-model of popular musical stardom entirely. If this happens, it will be a change which absolutely no one intended, and few anticipated, and not the result of any one emergent technology, but of a complex interaction between several. You can see the difference if you compare the music industry’s initial outcry against “home taping” with the situation today.

Whatever changes will come for film will be as unpredictable and as ongoing, but issues of intellectual property and piracy may ultimately be the least of them. The music industry’s product is, for want of a better way to put it, a relatively simple, relatively traditional product. Audio recordings just aren’t that technology-heavy. Though there’s one aspect of the digital’s impact on music that’s absolutely central to film: sampling. Sampling music is possible because the end-consumer of the product is now in possession of technologies equal or even superior to the technologies involved in producing that product. Human capital (that is, talent) aside, all the end-consumer-slash-creator lacks today, in comparison to a music-marketing conglomerate, is the funds required to promote product. The business of popular music, today, is now, in some peculiarly new way, entirely about promotion.
