Facebook started off GREAT! I singed up almost as soon as it was available to the general public (remember it was just open to university students at first).
At that time my timeline was basically text only and the content came from only my friends. It was like a fun online party -- not unlike online chat systems from the old days.
Then mysteriously all the people I enjoyed interacting with, disappeared from my timeline. Then I started getting content vaguely unrelated to my friends. Then meme photos I didn't want, ads and now basically just videos I hate and am bored of.
So the original concept is fine. It's just where we ended up that is mind numbing and alienating.
