See the Moments You Care About First

I want to see my friends' pictures. In the order they post them. I do not want a computer trying to determine which of my friends are more important to me, I assure you it will be wrong.
UGH I say.
I wonder how many instagram users have a manageable number of friends and can easily scroll and see all new photos. Now I'm worries I'll miss photos from friends because the feed re-order them.
These algorithms are likely prioritizing likes/favorites/followers/friends to determine what you probably want to see. People who are established in the ecosystem already (those who were "born rich") have an advantage. Meanwhile the guy who only averages one or two likes is destined for obscurity even if he or she drops a bombshell quality photo/comment/whatever.
People use and love social media because every like is an expression of someone paying attention to your life -- a reaffirmation that your moment is special to others in some way. If all of a sudden you get less attention because the system determines your contribution is not worthy of that attention you're more likely to leave the ecosystem.
I enjoy consuming content chronologically because I can go from [what I saw last] to [now] and never miss anything, but I guess most people follow too many things and/or don't have enough time to exhaust their feeds throughout the day.
I personally wouldn't get as much out of Hacker News if hckrnews.com didn't exist.
It's obviously not for user benefit, so I think it's mainly a monetezation thing. Once you aren't committed to showing things in chronological order, you can charge to appear at higher spots. This is what happened at Facebook -- work businesses and organizations put in to get organic "likes" was suddenly made worthless, but coincidentally here's how to purchase ads!
