It should be noted that Facebook is pushing very hard for more meaningful interactions in the form of Groups. These groups are taking an increasingly large amount of the newsfeed. Facebook's stated goal with these groups is to create meaningful communities. I think, at least to some extent, they are succeeding with this goal. Anecdotally, I know several people who say groups are the only thing keeping them on the network. Interestingly, the groups also dovetail well into the continued growth of their ad platform; they tend to be interest based, so they help with ad targeting.
