Now that you've seen what each social media aggregator can do, you're probably wondering which you should use. It depends on what you want to get from an aggregator, and how much time you are willing to invest to get those results.

FriendFeed does an excellent job of plugging all of your social output into a centralized river of social updates, but it's really only as good as your friends' willingness to adopt it (and creating imaginary friends is just too much work for something that's supposed to make your life easier).
