Content drift is how a piece of linked content may change over time such that what was once linked may in fact now be very different.

An article you link to may be corrected, opinions may be changed, content may be expanded or removed, a paywall may be put in the way, and yet the link keeps steadfastly pointing. Content drift, along with link rot — pages being lost — is one of the ways that the information we have come to rely on on the internet can be gradually undermined.

Here's a thread on content drift and link rot from Harvard's Jonathan Zittrain — at least, it was a thread on it when I wrote this. Also see: The Internet is Rotting.

The Streisand effect describes what happens when you try to censor or suppress information: it draws attention to it.

It’s named Streisand after Barbara Streisand tried to have an aerial photo of her house removed from a set of California coastline photos intended to document coastal erosion. Views of the photo apparently went from 6 to 420,000.

The Streisand Effect as a term was coined by Mike Masnick

Metcalfe's Law is: "The value of a telecommunications network is proportional to the square of the number of users of the system."
— Robert Metcalfe

This law explains a little of the remarkable power of a growing network. Each time you add a user or node to the network, the number of connections increases in proportion to the square of the number of users. So, in this simple example where every new node gets a connection to each of the existing nodes, you can see that, say, adding a single node to an 11-node network creates 11 new connections.

It’s a simplified example because in most networks, the value is not directly proportional to the number of connections as some connections or users may be more valuable than others, and usually, adding a new user wouldn’t create a connection to all existing users — say if it was in a different country, or people spoke a different language or just cared about different things. But nevertheless, you can see how a network quickly becomes valuable as users join.

So, Facebook has about 2 billion users…

Metcalfe was talking about telecommunications networks, and the basic proposition has been modified since it was formulated, including by Metcalfe himself.

Just because something is called a law doesn’t mean it is one. See
