I hear this claim made a lot, though I never see any warrants to back it up. Lots of people have expressed how Facebook is "so much harder to use," but never say where.
You've obviously never used Facebook then.
First, they separated the feed into two - the News Feed and the Live Feed. No one could fully understand what the News Feed even was other than a bastardized version of the more complete Live Feed. Then, no matter how many times you selected Live Feed, after a certain period of time, your home page would default back to the News Feed. Then, they changed their privacy settings so that if you once had a locked down account, the default settings would share more info than you were previously.
Now, with the most recent update, the Live Feed has just disappeared, the News Feed isn't complete, the Top Stories feed lists things completely out of order with new posts buried down on the page, the Live Feed has somewhat been broken out under the Friends -> Status Updates/Recently Updated section, but even that section is incomplete as I have friends who have made status updates today that don't display under any category. My lady friend whom I stalk with computer nerd like determination posted a new video of her animals that doesn't show up anywhere unless I click directly on her profile.
That enough examples for you?
