This made Facebook usable for me: https://github.com/jordwest/news-feed-eradicator

I can still use it as chat, address book, check events or particular updates/mentions, but I am not fed and infinite stream of mind sugar whenever I log in...

I still would love to completely quit... I tried a couple of times but I ended going back to contact particular people or to check out events. Facebook is turning into a basic social survival tool for foreigners living in metropolises and it kinda annoys me a lot.
