For example Hangouts makes me lose at least half a hour of productity a day but if I uninstalled it and never checked it then I would never talk to all of my friends on Hangouts which is not a trade-off that I am willing to take.
A lot of people say this one (usually about Facebook), but I don't understand it. If you want to talk to those friends, why doesn't it suffice to schedule spending time with them in the same way you would have done it in 2000?
