I kept mine around 150, but even then there was always a lot of crap in the news feed. No matter how many apps or whatever that I blocked, I could never get rid of it all (stupid "funny" pictures, scams, chain-posts, etc).

I have about 500. Not much "noise" since I took the time and effort to apply some Facebook's controls. Deeply embedded and sometimes obscure but they work for me.
