Encouraging the group chats I care about to move from Messenger to Signal. Its gone great so far, don't know why I left it so long.
Next step is clearing my profile and unfriending everyone. I meant to do this years ago.
I don't know if I will totally delete Zuckerberg from my life, but if I can whittle it down so I only use it to message strangers about picking up car parts, or to check local event details that aren't posted anywhere else, then I'll be pretty pleased with that.
