Do you hide the spammy stuff? I'm interested in nearly none of the apps on Facebook, but I really enjoy status updates and comments. So whenever I see something in the feed from an app I'm not interested in, I click the Hide button then choose to hide everything from that app. Two clicks, it's gone forever. Used to have to do that quite a bit, but now I've got most things blocked, so only about once or twice a week do I have to block a new app. Compared to dealing with spam in my email, it's no big deal at all.
