Another approach is to unsubscribe from everything (friends, groups etc.). You feed is empty, but you can still visit profiles/groups etc. but nothing will be pushed to you.
I did the same thing when I read about a plugin that was banned by facebook for allowing you to unsubscribe form everything and decided I was going to do it manually. Funny that facebook temporarily banned me from unfollowing people even though I was doing it manually, not using an app/plugin.
It's wonderful really.
