Generally speaking, Venmo peaks around 7 pm on the east coast of the US and stays fairly strong until about 3am, which is midnight on the west coast. The timing—and corresponding emoji—suggests the preponderance of Venmo transactions are people paying each other back for dinner and drinks.

Emoji use is markedly different at quieter times of the day. For example, the house emoji ranks highly from 7 am to 3pm EST. And the car and taxi emoji crack the top five between 5am and 8am EST.

Some of these data are skewed by messages containing a lot of emoji. The “pile of poop” emoji only holds the top spot in the midnight hour because a single payment used it 1,116 times.

On the usage patterns for the payment service Venmo, as interpreted by the emoji used to tag public transactions.

I like to think I'm young at heart, but the fact that Venmo is also a social network makes me feel old. Payment transactions are one form of community interaction, sure, but looking through my Venmo feed feels like peering through a fog of data pollution. Perhaps the next generation of kids really does live with their default life privacy settings toggled to public.

Speaking of the pile of poop emoji, it seems only a matter of time until someone releases an app that allows you to broadcast when you are taking a poop. It should be a mobile app just called Poop. I leave it to the design geniuses at Apple to figure out what type of haptic feedback a poop notification should emit on the Apple Watch.
