I only use Facebook for work - promoting nonprofit events, but its utility is diminishing as there is a growing share of people who flee Facebook and it's now creating double work as I both need to support Facebook, and email and the format of work are different. Facebook made it especially hard when they removed the ability to invite the same people from an old event - now I have to go thru my over 1,000+ and select who I should invite to which event, which is total nonsense! For personal stuff, I still use Skype and Viber to keep up with friends and family.
