I just joined Facebook a few months ago. I was afraid of it being a huge time waster with low signal to noise. So my expectations were quite low. Turns out the experience, with less than 30 Facebook friends, is even worse than I imagined it would be. The only thing I actually like about Facebook is the ability to reduce the amount of noise by blocking excessive posters and things like what video someone watched or what article they read. My main Facebook activity is managing noise.
