Facebook valued at $270 billion? NewsCorp buying MySpace for $580 million was sooo 10 years ago. #edchat

There’s a terrific piece in the current @NewYorker, Facebook Should Pay All of Us by Tim Wu. In it, Wu writes:

Facebook is […] widely assumed to have more data than anyone else. That data is useful for advertising, which is Facebook’s main source of revenue. But the data is also an asset. The two-hundred-and-seventy-billion-dollar valuation of Facebook, which made a profit of three billion dollars last year, is based on some faith that piling up all of that data has value in and of itself. It’s like a virtual Fort Knox—with a gold mine attached to it. One reason Mark Zuckerberg is so rich is that the stock market assumes that, at some point, he’ll figure out a new way to extract profit from all the data he’s accumulated about us.

…For the most valuable innovation at the heart of Facebook was probably not the social network (Friendster thought of that) so much as the creation of a tool that convinced hundreds of millions of people to hand over so much personal data for so little in return. As such, Facebook is a company fundamentally driven by an arbitrage opportunity—namely, the difference between how much Facebook gets, and what it costs to simply provide people with a place to socialize. That’s an arbitrage system that might evaporate in a world of rational payments. If we were smart about the accounting, we’d be asking Facebook to pay us.

Since NewsCorp bought MySpace for $580 million dollars in 2005, I have had so many conversations with students, parents, teachers, friends, family, and strangers about what I imagined NewsCorp was buying. Data. An ocean of freely shared data about its users from its users: Who are you? Who do you know? What do you do? Specifically, what are your likes and dislikes for bands, songs, cars, jeans, sodas, shampoos, computers, magazines, pizza toppings, television channels, narcotics, candidates, Friends characters? Where do you shop, hang out, watch movies? People freely and willingly uploaded any and all personal information and preferences to MySpace, and NewsCorps hoped to sift through swells of big data for advertising and internet marketing purposes. Six years later, NewsCorps sold MySpace for $35 million dollars in 2011. Ruh roh.

For almost two decades, I’ve working mainly with middle school students and teachers. During my time at The School at Columbia University, Don Buckley (Director of Innovation from 2006-2013) asked Cristina Martinez (our Systems Administrator) to set up an internal social network using Elgg back in like 2007 or 2008. To demonstrate that a social network is EMPTY until people populate it with information, we start every school year with a blank social network after archiving the previous year’s work. I constantly reinforce that everything posted online is either public or less public, so if you want something to be private, you should never upload it. Below are links to some posts I’ve written detailing specific annual curricular projects I’ve led using this in-house space, The Social Network:

8th grade SS students are creating faux profiles for the Founding Fathers on our internal @elgg social network

Alessandra Cozzi is the 8th grade Social Studies teacher at The School at Columbia University. She asked if we could have the students do some sort of social networking activity where they would make Facebook-esque faux profiles for the Founding Fathers. I told her that not only did we have an internal social network (powered by @Elgg), but our 8th graders had experience doing this last year as 7th graders when they created faux profiles for the annual Great Mathematician Project led by math teacher, Dr. Sabrina Goldberg. Easy peasy.

As per every academic year since 2007 or 2008, our server admin, Cristina Martinez, sets up a completely blank Elgg social network and archives the previous year’s work. This allows us to continue to use the space for annual projects, and it also reaffirms that a social network is a completely blank and empty space until users freely and willingly populate it with information. @DonBuckley says a social network is nothing until users answer the following questions: Who are you? Who do you know? What do you do?

Alessandra and I created a .csv file with usernames, profile names, common passwords, and faux email addresses for the 55 delegates, and I uploaded this .csv file to The Social Network (btw, we named our internal online networking space The Social Network way before the movie came out). Today, students edited their assigned Founding Father’s avatar and profile and then also linked with the other founding fathers.

For this activity, Alessandra used the lesson plan linked below, and students filled out the worksheet linked below:

Our new and improved Independent Reading Site is up and running at @The_School thanks to @finlaycm.

Cristina Martinez-Finlay is the Network Manager (and ever so much more) at The School at Columbia University. Last year, she decided to embark on a personal journey to revamp our beloved but kinda ugly Independent Reading Site which had been a labor-of-love Google Site that Marisa Guastaferro Mendez and I launched in 2007. We even won an award for it back in the day.

Marisa wanted an internal space for kids to keep track of their independent reading, post book reviews, and social network about literacy. We examined GoodReads, Shelfari, and other sites before deciding to just have an internal Google Site that anyone in our school community could access and edit. The site was alive and kicking and heavily used for 6 years. Then last year, Cristina showed me her pet project. She used Drupal to build the site (because, lordy, that woman knows Drupal), and she built up a site that is internal, robust, and legitimately way more attractive to use. The kids love it.

Today, Eve Becker (8th grade English) and I reminded the kids how to navigate the site, add books, join groups, post reviews, and comment on other people’s reviews. Cristina was there to answer questions too, and I’m glad the kids had a chance to appreciate her to her face.

Zen and the Art of 3D Printer Maintenance with @dorakio @kinderbanks. #edchat #edtech

7A81DC8B-111B-4B92-8995-605A2C26549AI just experienced one of the nerdiest weeks of my career. Our Bits From Bytes 3DTouch (@BitsFromBytes) wasn’t working well. It’s more gratifying to work with teachers and students on a design project when they know that the 3D structures and prototypes they create in Sketchup and Tinkercad will be printed in plastic. (Last year, Cristina Martinez and I supported a pretty awesome Greek Temple project that culminated in 5th graders literally outsourcing their designs to the East – in our case across the park to Jaymes Dec‘s 5th graders at the Marymount School on the Upper East Side!)

Since then, I tried to support some 3D printing projects, yet the 3D Touch was often frustratingly unable to print my designs fully. Right before we departed for winter break in December 2012, Don Buckley told me to learn out how to maintain the printer. While I consider myself handy, I would never fool myself into describing myself as an engineer, and I really didn’t need to be weighed down with the possibility of breaking a $4000 machine. However, I do what Don tells me, so I went forth unafraid. It took many hours over many days, but I think I know what I’m doing now.

I looked at pages and pages of information and FAQ from the BitsFromBytes resources link. First I learned how replace a delivery tube and load new filament. Then I experimented with raising/lowering the extruder nozzles and level the printer tray in order to print a successful raft. Once I had items printing regularly, I saw that we were running out of ABS filament and only had PLA left in our stash of replacement spools. So, I learned about the difference between ABS and PLA (ABS is more robust, PLA is cheaper), and learned how to change the target print temperature and RPM for each nozzle.

As it turned out, sometime in the 6th hour on the first day of my ministrations,  Akio Iida and Harry Banks noticed my omnipresence at the printer. They told me they had just finished a design project with their 3rd graders where students were tasked with redesigning a commonly used product (tissue box, pencil cup, x-box console, etc.) Watching me at the 3DTouch prompted Akio and Harry to come over and learn what I learned so that we could successfully start printing the children’s designs. The three of us spent much time together last week tweaking the machine, watching it work, and breathing in pastic-y fumes. The cow0rkers that breathe possibly cancerous toxins together, stay together. (Actually, the PLA material is plant-based and environmentally-friendly.)

Don Buckley has already placed the order for a Replicator 2X. Guess I better start reading the manual…
