Re: Who knows?
However, equally, anyone who's been on Facebook long enough will know that glitches do affect small groups of users, and even more intentional functionality changes are rolled out piecemeal, so one person's "I'm all right Jack" experience does not prove anything for the whole. Yes, people used to be a lot more fast and loose with what they put on walls versus private messages, but this does not necessarily represent the entire story given the (admittedly anecdotal) evidence to the contrary.
I for one was very bored when I got "timelined" and went though everything at the time to weed out unwanted content and still found some suspicious things yesterday. I'm not saying that's proof, because their screwy data model made things come and go during the weeding-out process, and I may have missed things, but then that's at least confirmation the data model is buggered so it really is anyone's guess what else could go wrong.
