I use a real photo on some other services like LinkedIn where I’m low frequency or one-note, but on twitter, any photo or cartoon face can only match the mood of like 10% of my tweets, and feels weird for 90%
I agree. Been meaning to replace my face with something interesting, like a bot that morphs the image a little every hour. Would be fun to see if one could design a morph and pace that maintains continuity from a casual observer’s POV while gradually changing substantially.
