Facebook buries all kind of content that subscribers have “opted into”.
It pushes group think.
It keeps forcing users to use “Top Stories” but permits them to temporarily set it to “recent” postings. The user is then given the reminder option to set it “back” to top stories.
If you are a “commercial” interest (anything that is a group, even if non-profit or even registered, band, artist, whatever), your posts are hidden from your followers (those who’ve even clicked the FOLLOW tab) to encourage the host to pay $$$ to “promote” a post (for example, if you have 200 subscribers, your post may be seen by only 11 people if you don’t cough up $5 or $10).
IF you can make your posts go viral (with a lot of likes, shares, and comments), then they will “trend” and appear on other peoples’ walls.
Hell, beyond all of that, you may be “friends” with 400 people, but you’ll only see the news feed items from about a dozen people that you have “engaged with” by messaging on FB, posting on their wall, etc.
FB has long been suppressing content from subscribers’ newsfeeds.
If you are interested in personal privacy, close your Facebook account. And for God’s sake, keep your kids off it.
Fairly broad charge, no?
