Like Entanglement: When twitter algo infers that you'll prob interact with tweets that someone else likes, so it keeps presenting them and you keep interacting with them, forming a feedback loop of creepy notifications.
(My feed is a partial replication of @MaureenBug's likes.)
Oh, actually, that's kinda a thing I hadn't thought about -- shadow friends? In any case, your likes/RTs make me question if I made the right choice by studying people. Maybe #TeamInvert has it right?
