One thing about this study as described in the article is it doesn’t really seem to be about “Facebook” persay but social media in general, it doesn’t seem to cover any of the newsfeed optimization stuff since it was done using data from the initial college rollout. Interesting nonetheless but I think it’s weird to attribute it to “Facebook” specifically, I mean, you sort of have to since they only covered Facebook in the research, but it mostly seems to be about “services that facilitate comparison to your peers.”
