In all professions there is one great equalizer... it's all about who you know. It is no different with the clandestine organization of ninjas. While a truly artistic and powerful ninja may be able to rise above the ranks of his compatriots, one can only make it so far without connections. As a result, some of the most sophisticated and cutting edge networking techniques have been developed and used by ninjas.
At the dawn of the 2000s the ninjas decided to foray into the networking capability of the internet. It began simply enough in 2002 with the development of a site called Friendster. The site was a modest success in the eyes of ninjas, but it lacked the necessary ability to customize user pages. Not to mention, word got out and the site was hijacked by shoguns...
In August 2003 the second phase of the networking plan was rolled out with MySpace. It originally solved all the problems the ninjas had discovered with Friendster. MySpace was entirely customizable, it allowed for privacy needs, and created a platform that could easily be embedded with hidden codes. That is, until the Pirates showed up. In their traditionally haphazard way of destroying everything pure, they infiltrated the site and plagued it with their heathen attitudes and pedophilia. (Fun side note: It was an effort to rid the world of these pirates that begat To Catch a Predator).
After the infiltration began, the ninjas decided they needed to find a new area for their networking... so they started working diligently with a couple of young Harvard students: Tyler and Cameron Winklevoss. It wasn't long after beginning work with the Winklevi that the ninjas were attracted to a much brighter and more capable student at Harvard. Their new partnership with Mark Zuckerberg proved quite powerful, as the development of Facebook provided the perfect platform for ninja networking.
Other networking sites have been attributed to the ninjas, but this is purely conjecture. In questioning known ninjas about the advent of Twitter, the sole response has been, "Ninjas don't tweet." LinkedIn has also been posited as a ninja formation, but no self-respecting ninja would look for the referential praise that one sees on sites like that.
Facebook will not be the last networking technique used by the ninjas... it certainly wasn't the first. After all, you never know when pirates will ruin everything again.
