How Do Facebook and Twitter Decide What to Show You?

Why is there so much junk in my Facebook News Feed? Can Twitter really win over new users with a change to its algorithms? And will Snapchat give rise to a new type of reality star?

Kara Swisher, guest host Kurt Wagner and special guest Justin Kan, a partner at Y Combinator and the founder of Justin.tv, answered all these questions and more on the latest episode of "Too Embarrassed to Ask."

In the first half of the show, Kara and Kurt talked about Twitter’s recently announced decision to show users more "best of" tweets when they come back from an absence, and why that has worked for Facebook. Thank you to everyone who submitted questions about social algorithms — remember that you can always send in questions about any topic to us by tweeting @LaurenGoode, @KaraSwisher or @Recode with the hashtag #AskRecode.

In the second half of the show, Justin Kan joined in to talk about his experiences as a serial entrepreneur and the pioneering online reality show Justin.tv, which he is relaunching as a project on Snapchat. Then, in "Too Embarrassed to Answer," Kurt challenged Justin with queries about Monica Lewinsky, the Crunchies and weird Internet comments.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
