Walter Benjamin termed the book ‘an outdated mediationbetween two filing systems’

On the Internet there are many collective projects where users interact only by modifying local parts of their shared virtual environment. Wikipedia is an example of this.[17][18] The massive structure of information available in a wiki,[19] or an open source software project such as the FreeBSD kernel[19] could be compared to a termite nest; one initial user leaves a seed of an idea (a mudball) which attracts other users who then build upon and modify this initial concept, eventually constructing an elaborate structure of connected thoughts.[20][21]

The promise also lies in doing things with the words, forging new links of association, remixing them. We have all the tools at our disposal to create commonplace books that would astound Locke and Jefferson. And yet we are, deliberately, trying to crawl back into the glass box.

The overall increase in textual productivity may be the single most important fact about the Web’s growth over the past fifteen years. Think about it this way: let’s say it’s 1995, and you are cultivating a page of “hot links” to interesting discoveries on the Web. You find an article about a Columbia journalism lecture and you link to it on your page. The information value you have created is useful exclusively to two groups: people interested in journalism who happen to visit your page, and the people maintaining the Columbia page, who benefit from the increased traffic. Fast forward to 2010, and you check-in at Foursquare for this lecture tonight, and tweet a link to a description of the talk. What happens to that information? For starters, it goes out to friends of yours, and into your twitter feed, and into Google’s index. The geo-data embedded in the link alerts local businesses who can offer your promotions through foursquare; the link to the talk helps Google build its index of the web, which then attracts advertisers interested in your location or the topic of journalism itself. Because that tiny little snippet of information is free to make new connections, by checking in here you are helping your friends figure out what to do tonight; you’re helping the Journalism school in promoting this venue; you’re helping the bar across Broadway attract more customers, you’re helping Google organize the web; you’re helping people searching google for information about journalism; you’re helping journalism schools advertising on Google to attract new students. Not bad for 140 characters.

Now, if I notice a moment in a past Are.na conversation that highlights the topic, I add it to the topic's channel. Now the text block sits in the middle of a Venn diagram — both part of a chat log and part of a curated selection from conversations I have.
