I like wit and jokes too, and you’re right, it’s certainly “different” to hear irreverent banter from a bank.
Whilst Monzo is riding an unstoppable wave of adoption driven by its technical progress, the self-indulgent “bantz” are probably fine.
But as soon as Monzo hits its first high-profile bug or scandal, the outside world might start to judge the iOS dev team’s irreverence and compare its release notes to those of a two-bit social media startup.
We might find “Mantham Dave” and his 250 Twitter followers aren’t as competent at PR damage limitation as they are at praising the bantz.
Just my two cents. I otherwise love Monzo and the iOS app is great.
