Facebook has made it easier to communicate, participate, pontificate, track down new contacts and vet romantic prospects.

Everything on Facebook, like an Instagram photo, is experienced through a soft-glow filter. And for all the noise, the pinging notifications and flashing lights, you never really feel productive on Facebook.
