Isn't friend recommendation mostly stuff like "people who follow you/you follow also follow X"? Maybe going one or two more follow hops, but not so far out that you need a global view of the social graph. If users of a decentralized network publish their following and follower lists, it should be pretty easy for a local crawler to check those hops.
