Everything that makes it big, like Facebook, seems to eventually grow out of its pants.
Hey we are making some cash, let's add this and that and bloat the system to the point where its nothing like it was, at least we will be rich!
Whatever comes around next will likely have the same issue. It will be great at first then history will repeat itself, even if the makers are aware of these issues, something will happen whether it be legal, social, etc.. There are always people that ruin it, which leads to changes, and then there is always tracking information and making money.
Everyone I know loved the old Facebook. Not a chat room, but just Facebook. Sure there were some issues, like annoying political posts that never change anyone's mind, news from the Onion that every old conservative believes (and will argue with you over) and the ridiculously stupid ones like Saturn will be the size of the moon in the night sky on April 22, 2019 - and people actually share it like its true!
However, it was great to keep tabs with each other and not scroll endlessly wondering if your browser will freeze before you find your friends post about the snail he found on his bedpost. Too many ads. There should be none in the news feed and less on the sidebars, hell my browser can only handle so much! I also want my feed in order, not based on an algorithm of what I should see first, nor should I have to click a drop down to sort the posts that way!
