Facebook tracks users, even those who don’t use it, says privacy report

Belgium’s data protection body has accused the social network of using plug-ins and cookies to follow users who have deleted their profile or never signed up for an account.That means the social media giant is breaching European law requiring users to choose whether to have tracking cookies placed on their device or not.

Pinnability: Machine learning in the home feed

Pinterest hosts more than 30 billion Pins (and growing) with rich contextual and visual information. Tens of millions of Pinners (users) interact with the site every day by browsing, searching, Pinning, and clicking through to external sites. The home feed, a collection of Pins from the people, boards and interests followed, as well as recommendations including Picked for You, is the most heavily user-engaged part of the service, and contributes a large fraction of total repins. The more people Pin, the better Pinterest can get for each person, which puts us in a unique position to serve up inspiration as a discovery engine on an ongoing basis.

Many, many Facebook users still don’t know that their news feeds are filtered by an algorithm

For heavy Facebook users, let alone social media gurus, the idea that Facebook’s news feed is filtered by an algorithm is very, very old news.

Nothing attracts news organizations like Facebook. And nothing makes them more nervous.

With 1.4 billion users, the social media site has become a vital source of traffic for publishers looking to reach an increasingly fragmented audience glued to smartphones. In recent months, Facebook has been quietly holding talks with at least half a dozen media companies about hosting their content inside Facebook rather than making users tap a link to go to an external site.

What Your Tweets Say About You

How much can your tweets reveal about you? Judging by the last nine hundred and seventy-two words that I used on Twitter, I’m about average when it comes to feeling upbeat and being personable, and I’m less likely than most people to be depressed or angry. That, at least, is the snapshot provided by AnalyzeWords, one of the latest creations from James Pennebaker, a psychologist at the University of Texas who studies how language relates to well-being and personality. One of Pennebaker’s most famous projects is a computer program called Linguistic Inquiry and Word Count (L.I.W.C.), which looks at the words we use, and in what frequency and context, and uses this information to gauge our psychological states and various aspects of our personality.
