Facebook's doling out new features to the masses this week. Their Google-Plus-alike Smart Lists will help you divide up the friends you care about. And their new email summaries will mush together the thousands of notifications you get from friends you don't.
Smart Lists, as you know, allows you to cull through your friends and divvy them up according to how they relate. That's not all that smart, so they'll automagically create lists for you based on associations—college, workplace, etc. You can also determine how you see them in your feed. Select your Work list, and you'll see your work buddies in your feed. Meanwhile, put someone in the Acquaintances list, and you'll simply see them less.
