How about not recommending people some algorithm thinks you should be "friends" with? If you can't bother to remember or type a person's name in and manually make that connection, chances are you're just fine without it anyway. I used Facebook in college back in 2004-2008 before they had any kind of suggestions and I had no problem amassing over 1,000 "friends." On a side note the whole site is totally different now and I don't use it anymore.
