PageRank
Mathematical PageRanks for a simple network, expressed as percentages. (Google uses a logarithmic scale.) Page C has a higher PageRank than Page E, even though there are fewer links to C; the one link to C comes from an important page and hence is of high value. If web surfers who start on a random page have an 85% likelihood of choosing a random link from the page they are currently visiting, and a 15% likelihood of jumping to a page chosen at random from the entire web, they will reach Page E 8.1% of the time.

I do not know what to write. I am sitting here staring at the screen, running sentences in my head, and turning my music on and off. Earlier I went foraging for food (in hopes of sparking some magical words), but ended up getting distracted by Arrested Development for 20 minutes. This happens just about every time I sit down to do anything. I’ll probably go play the guitar between this paragraph and the next. Of course this is a familiar situation.
Multiple Models for Social Media Businesses: Tech News «
Twitter’s move to a more “centralized,” broadcast-media-style model, and Facebook’s shift away from that approach, spark some interesting thoughts about what it takes to succeed in social media. As I discuss in a post at GigaOM Pro, the strategy a company chooses will align it with a particular revenue model. With a site-centric strategy, you’re in the eyeball business. That means you’re either selling to your audience or selling the audience itself (to advertisers, marketers, retailers).

The Small-World Phenomenon: An Algorithmic Perspective 1
Jon Kleinberg 2 Abstract: Long a matter of folklore, the ``small-world phenomenon'' -- the principle that we are all linked by short chains of acquaintances -- was inaugurated as an area of experimental study in the social sciences through the pioneering work of Stanley Milgram in the 1960's. This work was among the first to make the phenomenon quantitative, allowing people to speak of the ``six degrees of separation'' between any two people in the United States. Since then, a number of network models have been proposed as frameworks in which to study the problem analytically. One of the most refined of these models was formulated in recent work of Watts and Strogatz; their framework provided compelling evidence that the small-world phenomenon is pervasive in a range of networks arising in nature and technology, and a fundamental ingredient in the evolution of the World Wide Web.
Five Ways to Make Change Easier : The World
There's a simple reason that change efforts are difficult, and it's not that people are lazy or resistant or stupid. Change is hard because February 16, 2010 There’s a simple reason that change efforts are difficult, and it’s not that people are lazy or resistant or stupid.

100 Email Hacks
It’s hard to believe that in 1998 when the movie “You’ve Got Mail” came out, people actually looked forward to opening their inbox. Back then “Inbox Zero” was an insult (“You have no friends, Inbox Zero-boy”). Now it’s considered a mythical utopia, a place where only a select few can ever hope to visit, and only very briefly. At SaneBox, we’ve done lots of research and thinking on ways to get better at email, and compiled this list of 100 hacks (i.e. tricks, tips, apps, methods) which will let you get to Inbox Zero every day.
Nash equilibrium
In game theory, the Nash equilibrium is a solution concept of a non-cooperative game involving two or more players, in which each player is assumed to know the equilibrium strategies of the other players, and no player has anything to gain by changing only their own strategy.[1] If each player has chosen a strategy and no player can benefit by changing strategies while the other players keep theirs unchanged, then the current set of strategy choices and the corresponding payoffs constitutes a Nash equilibrium. The reality of the Nash equilibrium of a game can be tested using experimental economics method. Stated simply, Amy and Will are in Nash equilibrium if Amy is making the best decision she can, taking into account Will's decision while Will's decision remains unchanged, and Will is making the best decision he can, taking into account Amy's decision while Amy's decision remains unchanged.
