I only used Facebook when it very first started and my University was added to the list of included Universities, and I didn't use it much since I didn't really trust it. Many years later (just last year), after leaving a job and my employees wanting to keep in touch with me, I started to occasionally log in just to check for messages, and it was a completely different place as far as I could remember. Nothing seemed familiar anymore, the "clean myspace clone" aspect was pretty much gone, since the social part was pretty much gone in favor of the feed. The rest is still there, but it seems like an afterthought now as opposed to what gets shown on the feed.

It used to be that you'd see the latest things from your friends and pages. Now you see what Facebook thinks you'll want to see from your friends and what some pages paid to advertise at you.

If you haven't liked something by that person in a while, you're unlikely to see anything by them if you only log in once every few months. And if you thought you'd see updates from a page after subscribing... well, you will if the page keeps paying for adverts.

Disclaimer: I don't use Facebook anymore, if I'm wrong please correct me!
