My Facebook experience became far more pleasant when I found out that updates for Farmville and other games can be hidden, and how to do it.
It is fairly customizable so I don’t see the point in defriending (how is this word not in my spellcheck dictionary yet) anyone unless they are seriously misbehaving. I haven’t even defriended the aunt who no one talks to anymore because she became a religious nut and only posts bible passages and game requests.
Personally I only check the new feed if I’m bored. Usually I just check notifications, or if I haven’t heard from someone specific in awhile I’ll like-spam their page. I used to group friends by type but then fb changed how they did that and I haven’t bothered to redo it.
The only thing that annoys me is the app doesn’t have all the features of the browser version.
