Here is an eye-opening article from data scientist Vicki Boykis outlining the number of ways in which Facebook collects data about its users. It’s called: What should you think about when using Facebook?

One of the more surprising tidbits from Boykis’ article is that Facebook collects keystrokes. That means if you start typing a status update but never actually post it, that information is still fair game.

Facebook previously used this data for a study on self-censorship. That sounds like like a fascinating study, but I’m sure the thought is also scaring many of you if you care about privacy.

Here is a quote from the article that gets at the core of what is going on:

“The fundamental purpose of most people at Facebook working on data is to influence and alter people’s moods and behaviour. They are doing it all the time to make you like stories more, to click on more ads, to spend more time on the site.”

A worthwhile read. And in case you didn’t already know, if you go to Settings -> Download a copy of your Facebook data, you can get a pretty good dump of your activity, including every private message you’ve ever sent on the platform.

Last year, social media company Foursquare predicted that Chipotle would see a ~30% drop in its Q1 2016 sales. It knew this because the geo-location data from people using its app (check-ins and passive visits) was also down. They had figured out the relationship between foot traffic and sales. I think I wrote about this in the first half of last of year.

Not surprisingly, lots of companies – including those on Wall Street – are now starting to pay attention to data sets such as these. Matt Turck wrote a great blog post about it this morning, called: The New Gold Rush? Wall Street Wants your Data. Here’s an excerpt:

That a social media company could be building a data asset of immense value to Wall Street is part of an accelerating trend known as “alternative data”. As just about everything in our lives is getting sensed and captured by technology, financial services firms have been turning their attention to startups, with the hope of mining their data to extract the type of gold nuggets that will enable them to beat the market.

The opportunity is open to a wide range of startups.  Many tech companies these days generate an interesting “data exhaust” as a by-product of their core activity.  If your company offers a payment solution, you may have interesting data on what people buy. A mobile app may accumulate geo-location data on where people shop or how often they go to the movies.  A connected health device may know who gets sick when and where.  A commerce company may have data on trends and consumer preferences. A SaaS provider may know what corporations purchase, or how many employees they hire, in which region. And so on and so forth.

Uber just announced that it will be providing access to the (anonymized) traffic flow data generated from its over 2 billion rides. This new product is called Uber Movement and the goal is to help cities make better infrastructure decisions. Because indirectly, that also benefits them. 

Here’s an excerpt from TechCrunch:

“We don’t plan infrastructure, we don’t plan cities, we’re never going to do that,” explained Uber Product Manager Jordan Gilbertson in a briefing. Not controlling those aspects of Uber’s business means that it must do whatever possible to influence their improvement indirectly, which Movement can certainly help to do. More efficient transportation in a city in general means more efficient Uber service delivery, happier customers and better usage rates.

You can request access to Uber Movement today. But the service will be made available first to city planners and policymakers, and then to the general public. I would be very curious to see what the data reveals for Toronto, as well as for other cities.
