Value of Facebook to me has eroded over last 2 years or so primarily because of messengers such as whatsapp and privacy concerns.<p>I use linkedin to stay in touch with colleges, WhatsApp to stay in touch with close friends and family, share pictures etc. and I ignore most other people in my life.<p>Facebook remain the source of news and interesting links that people share but I am pretty sure someone will fill that need better than facebook sooner or later.<p>P.S. I use Facebook extensively to run ad campaigns for my apps. But I am not counting that as use.
