I mean, to be honest, I feel like it's the quality of the content in there. I used my old phone (the one I use for apps like threads) to get a threads account and people are using Threads as if they're using instagram.
For example, you see a pocture of someone or a drawing, you get into the post to see the 45 comments people left and all of them are:
Comment #1: "Magnificent 🥰😍" #2: "Amazing 🤩" #3: "WOW!! 🔥🔥"
And so on.
At least in twitter there is more "discussion" (albeit toxic and usually useless) or at least more people sometimes talking about interesting things.
I wonder if advertisers have been leaving Reddit and if so, how many? I've honestly never seen a social media website/company ask for advertisers like this tbh.
I'm not a lot on social media to begin with, so I'm not sure.
