Haven't posted in ages, but thought this would be fun, and that someone here might appreciate it.
I've been working from home since the start of COVID, and I generally keep on some background media while working - podcasts, tv shows, music, etc. About 8 months ago YouTube suggested a replay of an SC2 pro match. I played SC2 for a short while during beta, but to my knowledge, I haven't done, said, or watched anything that would warrant YouTube to think I would be interested in SC2. This is because I didn't know I was interested in SC2.
Out of curiosity, I watched that replay. I now watch this shit all day and actively watch these guys stream on Twitch. All because YouTube suggested one video to me. I'm not going to pretend to know how YT's suggestion algo works, but I like to think that if any number of things happened for me to not watch that video, that it would have never been suggested again.
