I noticed recently that FB introduced a "configure your feed" utility. When I clicked into it, it appears as though it algorithmically determines the people who you most want to see content from, from highest probability to lowest. Interestingly, all of the interesting groups and news organizations and the like -- the stuff I care about -- was at the very bottom. I moved all of that stuff to the top and it fixed my feed for the most part.

But that said, there is no substitute for a fixed "most recent first" setting that doesn't reset, and frankly, the fact that it DOES reset is extremely creepy and leads me to use facebook much less often that I would otherwise.
