The Most Popular Hashtag on Twitter Is #FF and the Most Popular Emoji Is

The emoji means “tears of joy,” something a few longtime Twitter employees might be shedding as their baby turns 10 years old this week.

It’s also the most popular emoji on Twitter, according to the company, with 14.5 billion symbols tweeted to date. Meanwhile, the “most tweeted hashtag tradition” is #FF, short for “follow Friday,” with 539 million mentions.

Here are some of the other silly stats Twitter released today to commemorate the anniversary. Fun!

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 reasons that we can't rely only 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. We can’t do that if we have a paywall.

That’s why we also turn to you, our readers, to help us keep Vox free. If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today?
