The whole social aspect of Venmo is one of the stupidest things to have ever been created. I use Venmo because it's the most widely used platform, but all of my transactions are private.
Do people even scroll through the public feed of their friends? Why does anyone care that their friend paid another friend (who they likely don't even know) $10 for a burger and fries? So fucking dumb.
It's weird you mention that, my girlfriend keeps getting eggplants bought for her on her Venmo and it's kind of cool and all, but she doesn't even use the money for veggies, lol.
I use venmo only sparingly, but whenever I do I take a peek at that page, and see mostly old college friends I no longer talk to paying people I dont know for pizza or rent or whatever. It always feels creepy.
