>And then a few months back I just could not take my eyes off of Instagram reels. This feature wasn't there before I think. I was just completely hooked. It was pretty interesting. I had to delete my instagram off of my phone.

Sounds like they started showing you different kind of content. I never got into Instagram because I'm just not into the kind of content that gets published there. Not arguing that content presentation isn't a factor here, but I would argue it's the content that's addicting and even if you remove the suggestion algorithms and just did social sharing/recommendations you'd still end up with similar results - viral stuff got shared in chats/groups/mail chains/etc. now it gets served up to your feed directly.

Not saying suggestion algorithms don't improve the experience if they work, but I wouldn't really attribute that much value to them, ultimately we have an industry of influencers trying to create content that will grab your attention.
