Qualities of an Entrepreneur - Elon Musk

Why we need Eigenvector Centrality

“Don Corleone did not have many strong ties. He was a man of few words, yet he could make an offer you can’t refuse. Don Corleone surrounded himself with his sons and his trusted capos, who in turn, handled the day to day management issues of the family.* If we used network metrics such as degree centrality, betweenness or closeness, Don Corleone would be largely invisible in the network—which is the point of how his organization was created. Positions such as Don Corleone’s can have an immense power; by knowing well connected people, they can exploit this information and information asymmetry to further their own plans, while staying largely in the shadows.” => Don has a high Eigenvector Centrality score

let's rank the value of a URL by comparing the number of times it was tweeted

I would love to get the actual PageRank score assigned by Google, unfortunately it's proprietary. The various PageRank scores available on the internet are all integers (0-9), which makes it hard to form a comparison metric. Alternatively, we could build a frequency-histogram that looks at the number of times a link was tweeted on Twitter. Obviously "cheerleading" is not the best metric, so I'm open to suggestions! Let's make a REST call to Topsy: http://code.google.com/p/otterapi/wiki/Resources#/stats via http://hurl.it/ using url = http://otter.topsy.com/stats.json?url=http://www.nytimes.com { "response": { "all": 656204, "toplevel": "top1k", "contains": 0, "influential": 308, "topsy_trackback_url": "http://topsy.com/www.nytimes.com/?utm_source=otter" }, "request": { "response_type": "json", "resource": "stats", "parameters": { "url": "http://www.nytimes.com" }, "url": "http://otter.topsy.com/stats.json?url=http%3A%2F%2Fwww.nytimes.com" } } What's interesting was that 308 "influential" [whatever that means] users tweeted this link…
