I've noticed, by the way, that recently Twitter feeds to both Facebook and my own site omit conversations or tweets to specific people. Is it desirable that those not be forwarded? My own Twitter conversations are always about issues, not about personality stuff.
I have not noticed any big changes in Timeline or my own Facebook news feed specifically today (or yesterday). Maybe they were already in effect on my account. My news feed seems to be driven off "Likes" and possibly my own surfing (since I allow tracking). It may be affected by the substance of my own blogs and sites.
