You can opt out of all apps. That includes chat and Tweets and remote/phone posting, everything gets turned off. You can turn them on one at a time as you try to use some feature that was disabled if you want that feature on. I had to opt out, my nieces and sisters are casino/farmville nuts and that junk was 90% of what was showing up. Dig around in your account, sorry I couldn't tell you where I found the switch - but try hovering over the upper right corner of some app "news" and you may see the option there.
