I am baffled any time I’m on facebook how horrid it is. Loads insanely slowly, won’t accept picture uploads at random, randomly doesn’t let you share to people in your friends group (it will just hide people for no reason). Such a terrible website. Sadly I have to stay on it for friends and music reasons (there is nothing else anyone I know uses) but man, it’s crazy how badly they want you to install their spyware app so you don’t use the browser version.
It is Optimised.
Just not optimised for efficiency or ease of use.
It is optimised for extracting as much personal metadata as possible, feeding as many ads as possible, monopolising users attention and manipulating political opinions.
ya, it wasn’t ever created with the user in mind. Websites that are horrible to use generally need ton of external analytics, facebook does it all in-house.
