Over the past several months, I noticed that I was missing friends' updates in my Facebook News Feed. Specifically, I wasn't seeing many of my wife's posts in my Facebook News Feed unless I visited her Facebook page.
My friend, Rich, told me that Facebook had defaulted to showing the updates only from friends that I interacted with most often. I spent a good deal of time trying to track down this setting without any luck.
This afternoon, I asked Rich where to find the Facebook setting that controlled whose updates appear in my Facebook News Feed. It took him a little digging, but he found it and sent the details to me.
