Over the past few years, I've observed that many of my friends on Facebook have dropped off or become very rarely active. It's often that there aren't even enough new posts in a day to fill the screen and I see older posts from older days.

Conversely, on Twitter I started following a variety of journalists and otherwise interesting people, and there's always a ton of stuff to read, but relatively little from people I've met in real life, and for those, they tend to post more professional and little or nothing personal.

I'm curious if others have made similar observations. Like, has the Facebook "news feed of your friends" idea just completely died off?
