It is also possible now to make individual Facebook status updates visible only to a selected group or custom-defined-on-the-spot subset of your friends list. I tried it, and it seemed to work. Now, if I only *trusted* Facebook not to screw it up--which I don't.
Yeah, I have even more FB friends (currently 554). I tried to define a friends group for postings of the same level of personal content I'd use for Facebook, but was defeated by the utterly abysmal user interface (scrolling through the entire list in a tiny window that you can't enlarge). I gave up. If you *do* manage to define a group that encapsulates some community in that way, it's actually pretty easy after that (until you want to change the list, which sends you back to UI hell).
