Despite her claim here, it's possible that she missed her friend's post because her surveillance of her own feed is likely to be imperfect, especially if she has a non-trivial number of friends.
edit: I bring this up because, ostensibly, the whole point of FB's (or any social network's) "most important" algorithm is to mitigate the problem of how "most recent" can be too overwhelming to consume if you have a non-trivial number of friends. If OP has a lot of friends, such that there are a few dozen new items per day on her newsfeed, even if she were meticulously reading her feed, daily, there's no guarantee that she didn't miss the post because of imperfectly skimming them. That no one else in her social circle noticed isn't much proof since, as a mutual friend admits, they don't know how many of them are active on FB: https://twitter.com/FRENDEN/status/942918637576441857
That said, I swear I've seen FB's algorithm point out users who have posted for the first time in a long while. This kind of notification/signal presumably would not be part of a "Most Recent" timeline:
