It's definitely worth confirming that you have the right username before sending funds, and I think newcomers are more likely to make that mistake. If you're paying someone or receiving payment on PCF I would recommend giving the other person your username, not have them try to find you by name. It also helps when you are dealing with the same people over and over (e.g., paying money back and forth to poker buddies or friends) because those people will show up in your list.
One other complaint I have about Venmo, and which is a difference from PayPal worth being aware of, is if you're trying to make a payment that exceeds your balance it will draw the full payment amount from your linked account rather than first use your Venmo funds. For example, if you have $300 in your Venmo and pay someone $250, it will obviously take that money from your balance BUT if you only have $200 in your Venmo and go to pay someone $250, it will leave the $200 in your account and pull $250 straight from your associated checking. Of course, you can then deposit that $200 back into your account, so there's not necessarily a net financial impact, but it can be an unintended consequence.
