The Internet map

The map of the Internet Like any other map, The Internet map is a scheme displaying objects’ relative position; but unlike real maps (e.g. the map of the Earth) or virtual maps (e.g. the map of Mordor), the objects shown on it are not aligned on a surface. Mathematically speaking, The Internet map is a bi-dimensional presentation of links between websites on the Internet. Every site is a circle on the map, and its size is determined by website traffic, the larger the amount of traffic, the bigger the circle. Users’ switching between websites forms links, and the stronger the link, the closer the websites tend to arrange themselves to each other. Charges and springs To draw an analogy from classical physics, one may say that websites are electrically charged bodies, while links between them are springs. Also, an analogy can be drawn from quantum physics. Anyway, the real algorithm of plotting The Internet map is quite far from the analogies given above. Semantic web The Internet Phenomenon

styleguide - Style guides for Google-originated open-source projects Pinterest fights Chinese cyber-squatter A Chinese man has been snapping up dozens of domain names related to popular American start-ups and is seeking to trademark some of the names in the US and China. Qian Jin of Nanjing, China, has applied to register marks like Foursquare, Twitter, Quora and Instagram and has also bought dozens of websites like Pinterests.com and Pinterest.de Qian’s activities are described in a lawsuit filed by Pinterest last week in San Francisco. In its complaint, the popular image site says the defendant is a “serial cyber-squatter who has registered and owns hundreds of infringing domain names.” While this type of cyber-squatting has been around for years, the Chinese efforts stand out because they appear to systematically target up-and-coming internet firms, and because of the trademark applications. While firms like Pinterest can challenge the trademark filings in the US if they are not in good faith, the situation in China is murkier. Pinterest Complaint

Don't give away your product for free... …unless you plan to keep it free forever. The Cost of Free Doughnuts, a story on NPR shows what happens when you make something paid that was once free. During WWII, the Red Cross, which used to give away free coffee and doughnuts started charging servicemen for doughnuts at the behest of the US Government. Veterans still remember this 70 years later! The reporter goes and finds some veterans and asks about the Red Cross and they go OFF about having to pay for doughnuts. The reason that it sticks in someone’s mind is because going from free to paid is a “Categorical Change”. The psychological difference between $1 and $2 is minuscule compared to the difference between ZERO and $1. Zero isn’t a pricing strategy, it’s a different category A popular strategy for SaaS products is to be free until you figure out pricing. Here’s why: Charging money establishes the value of your product When starting something new, you should try to find out if it’s valuable. Just think about your own behaviors?

Clipix Wants To Be A Pinterest For The Real World Does the world really need another visual bookmarking service? After all, we already have Pinterest and all of its clones. Clipix, however, believes that it has found a way to differentiate itself from the competition. The service, which is coming out of beta today, feels a bit like a hybrid between Evernote and Pinterest, with a bit of Pearltrees thrown in for good measure. This mix, as Clipix founder and Wall Street veteran Oded Berkowitz told me earlier this week, is meant to keep the service flexible and allow users to, for example, easily create a folder for all the research they are doing about a purchase, as well as a copy of the warranty after the purchase. Overall, the service, which has been in beta since February, feels very feature-complete already. One nifty tool that sets Clipix apart from the competition is its price drop alert tool (the company has a patent pending for this technology).
