Our working definition of a digital platform (with a hat tip to Harold Feld of Public Knowledge) is an online service that operates as a two-sided or multi-sided market with at least one side that is “open” to the mass market

What Facebook knows about you
On Facebook's map of humanity, the node for "you" often includes vast awareness of your movements online and a surprising amount of info about what you do offline, too. The company has near-total awareness of every move you make on its website or in its apps. Facebook does scan your chat messages, but it isn't exactly reading them — it runs an automated scan for child pornography and other banned content. Facebook sees you less thoroughly outside its own digital turf, but it still sees a lot.

What Makes Sen Warren’s Platform Proposal So Potentially Important.
March 8, the Presidential campaign of Elizabeth Warren, not to be confused with the actual office of Sen Elizabeth Warren (D-MA), announced Warren’s plan for addressing the tech giants. What makes Warren’s contribution a potential game changer is that she goes well beyond the standard “break ’em up” rhetoric that has dominated most of the conversation to date, and focuses on sustainable sector specific regulation. What makes it so important and smart structurally is that the proposal:

30 years on, what’s next #ForTheWeb?
Today, 30 years on from my original proposal for an information management system, half the world is online. It’s a moment to celebrate how far we’ve come, but also an opportunity to reflect on how far we have yet to go.To tackle any problem, we must clearly outline and understand it. I broadly see three sources of dysfunction affecting today’s web:
Facebook’s new move isn't about privacy. It’s about domination
People in China use WeChat for everything from sending messages to family to reading news and opinion to ordering food to paying at vending machines to paying for a taxi. For Facebook’s CEO, Mark Zuckerberg, WeChat is both his greatest challenge and the model for the future of his company. WeChat is what Facebook has yet to become.

A Democratic agenda for regulating tech: Follow the Republican Roosevelt
With Democrats in control of the House of Representatives, at least one chamber of Congress could be poised to meaningfully update consumer and competition protection rules for the internet age. In doing so, they would be well advised to follow Republican Theodore Roosevelt’s efforts in the industrial age. Today, the internet barons are making the rules for the new economy. Roosevelt’s admonition is simple: There must be a “still higher power” that makes rules for the protection of the public interest.
Elizabeth Warren: Here’s how we can break up Big Tech
America’s big tech companies have achieved their level of dominance in part based on two strategies: 1) Using Mergers to Limit Competition Using and 2) Proprietary Marketplaces to Limit Competition.

Examining Problems, and Solutions, for Journalism in the Age of Online Platforms
On Feb 25, 2019, Free Press released Beyond Fixing Facebook. The authors, Timothy Karr and Craig Aaron, look beyond Facebook to address a deeper problem infecting the entire "attention economy": the abuse of targeted advertising.

Inside Facebook's War on Hate Speech
When it comes to figuring out how Facebook actually works—how it decides what content is allowed, and what isn’t—the most important person in the company isn’t Mark Zuckerberg. It’s Monika Bickert, a former federal prosecutor and Harvard Law School graduate. At 42, Bickert is currently one of only a handful of people, along with her counterparts at Google, with real power to dictate free-speech norms for the entire world. In a meeting room called "Oh, Semantics", she sits at the head of a long table, joined by several dozen deputies in their 30s and 40s.

Statement on the Code of Practice against disinformation: European Commission asks online platforms to provide more details on progress made
The European Commission published reports by Facebook, Google and Twitter covering the progress made in January 2019 on their commitments to fight disinformation. These three online platforms are signatories of the Code of Practice against disinformation and have been asked to report monthly on their actions ahead of the European Parliament elections in May 2019.
The President and Congress Are Thinking of Changing This Important Internet Law
President Donald Trump’s technology adviser Abigail Slater suggested that Congress should consider changes to a little-known provision of the Communications Decency Act called Section 230. Section 230 has a simple, sensible goal: to free internet companies from the responsibilities of traditional publishers.
