– Cluster Coefficient: This will give you an idea of how cohesive your network is. It’s pretty simple, just how many links you have in your network as a percentage of total potential links (which you can calculate by n(n-1)/2)

Finally, I would encourage you to read “6 Degrees” by Watts and “Linked” by Barabasi. Both are primary network theory pioneers and give accounts that are much more readable and informative than journalists write.

A tribe would eventually choose a host based on convenience (members are already using it, easy navigation, rapid sharing of communication, etc.), integration (Facebook Connect, Google Connect), and to some extent, available applications for members to use while being logged on to the network. Facebook excels in all three

Laugh all you want, fuzzball, but Google is changing how YouTube uploaders manage comments on their videos. The new system, which began rolling out to a limited number of uploaders on Tuesday, favors relevancy over recency and introduces enhanced moderation tools. The new commenting system, which is powered by Google+ and was developed in collaboration between the YouTube and Google+ teams, provides several new tools for moderation, said Nundu Janakiram, product manager at YouTube. It will default to showing YouTube viewers the most relevant comments first, such as those by the video uploader or channel owner. "Currently, you see comments from the last random person to stop by," Janakiram said. "The new system tries to surface the most meaningful conversation to you. We're trying to shift from comments to meaningful conversations," he said.

He explained that three main factors determine which comments are more relevant: community engagement by the commenter, up-votes for a particular comment, and commenter reputation. If you've been flagged for spam or abuse, don't be surprised to find your comments buried, but that also means that celebrities who have strong Google+ reputations will be boosted above others. There's more to the system than just relevancy, though. Because the system is powered by Google+, comments made on posts with YouTube links in the social network will show up on YouTube itself. So, you'll see comments from people in your Google+ Circles higher up, too. Just because it's powered by Google+ doesn't mean that you'll lose your YouTube identity, though. "You are still allowed to use pseudonyms," said Janakiram, whether you're "a Syrian dissident or SoulPancake". Another feature, and one that speaks directly to YouTube's goal of fostering conversations, is that you'll be able to comment publicly or privately to people in your Circles. Replies will be threaded like Gmail. The hope is that new moderation tools will make it easier for video owners to guide the conversation, Janakiram explained. "There have been challenges in the past with certain comments and what's been shown there."

The Intercept published an expose on the NSA's XKeyscore program. Along with information on the breadth and scale of the NSA's metadata collection, The Intercept revealed how the NSA relies on unencrypted cookie data to identify users. As The Intercept says: "The NSA’s ability to piggyback off of private companies’ tracking of their own users is a vital instrument that allows the agency to trace the data it collects to individual users. It makes no difference if visitors switch to public Wi-Fi networks or connect to VPNs to change their IP addresses: the tracking cookie will follow them around as long as they are using the same web browser and fail to clear their cookies." The NSA slides released by The Intercept give detailed guides to understanding the data transmitted by these cookies, as well as how to find unique machine identifiers that analysts can use to differentiate between multiple machines using the same IP address. We've written before about how spy agencies piggyback on social media account data to find Internet users' names or other identifying info, and these slides drive home the point that HTTP cookies leave users vulnerable to government surveillance, since any intermediary (or spy agency) can read the sensitive data they contain.

Worse yet, most of the time these identifying cookies come from third-party sources on webpages, and users have no meaningful way to opt out of receiving them (short of blocking all third party cookies) since advertisers (the main server of these types of cookies) refuse to honor the Do Not Track header.  Browser makers could help address this sort of non-consensual tracking by both advertisers and the NSA with some simple technical changes—changes that have been shown to reduce the number of third party cookies received by 67%. So far, though, they've been unwilling to build privacy protecting features in by default. Until they do, the best way for users to protect themselves is by installing a privacy protecting app like Privacy Badger, which is designed to block these types of uniquely identifying tracking cookies, or HTTPS Everywhere to block the transmission of HTTP cookies.
