Bigger is not necessarily better
Facebook is now apparently encouraging users to delete friends.
Possibly, they are realizing people with too many friends are not seeing relevant posts from their "real" friends in their newsfeed. With their rollout of Graph Search, connections with only "real" friends will be even more important.
This is the second time in recent weeks a social network has come out with a bigger-is-not-better policy. Niche site A Small World closed to new members to focus on "the integrity of their membership".
Questions to ponder:
Could this be the end of vanity metrics, like the raw number of Twitter followers (rather than engaged followers in the target audience)?
How will this trend to reduce network size impact Klout scores?
